Douluo: I Have a Big Golden Bell

Faraday Electromagnetic Induction The phenomenon of electromagnetic induction refers to the phenomenon of induced electromotive force due to changes in magnetic flux. For example, when a part of a conductor in a closed circuit moves to cut magnetic field lines in a magnetic field, a current will be generated in the conductor. The generated current is called induced current, and the generated electromotive force (voltage) is called induced electromotive force. The direction of the electromotive force in the law of electromagnetic induction can be determined by Lenz's law or the right-hand rule. Contents of the right-hand rule: Stretch your right hand flat so that your thumb is perpendicular to the four fingers. The palm of your hand faces the N pole of the magnetic field. The direction of the thumb is consistent with the direction of movement of the conductor. The direction pointed by the four fingers is the direction of the induced current in the conductor (the direction of the induced electromotive force is the same as the direction of the induced current). Lenz's law states that the magnetic field induced by the current must hinder the change of the original magnetic flux. In short, as the magnetic flux becomes larger, the current generated tends to become smaller; and as the magnetic flux becomes smaller, the current generated tends to become larger. The magnitude of the induced electromotive force is determined by Faraday's law of electromagnetic induction; e(t) = -n(dΦ)/(dt). For dynamic situations, E=BLV can also be used to find it. Faraday's experiment showed that no matter what method is used, as long as the magnetic flux passing through the closed circuit changes, there will be current in the closed circuit. This phenomenon is called electromagnetic induction, and the current produced is called induced current. Faraday concluded the following law based on a large number of experimental facts: The magnitude of the induced electromotive force in a circuit is proportional to the rate of change of the magnetic flux passing through the circuit. If the induced electromotive force is expressed by , then , this is Faraday's law of electromagnetic induction. If the closed circuit is a coil of turns, it can be expressed as: . In the formula, is the number of turns of the coil, is the change in magnetic flux, the unit is , is the time it takes for the change to occur, the unit is , is the induced electromotive force generated, the unit is . Calculation formula for the magnitude of induced electromotive force: (1) Among them, is the induced electromotive force generated, is the number of turns of the coil, is the change amount of magnetic flux, and is the time taken for the change; (2), it is applicable when the conductor moves to cut the magnetic field line, where is the magnetic induction intensity, the length of the conductor, is the speed of cutting the magnetic field line, is the angle between the direction of and , (3) , is generally used to find the maximum induced electromotive force of an alternator, is the peak value of induced electromotive force (4), one end of the conductor is fixed to rotate and cut, is the angular velocity (rad/s), V: speed (m/s)} Magnetic flux calculation formula: Magnetic flux, is the magnetic flux (Wb), is the magnetic induction intensity (T) of the uniform magnetic field, It is the area (m2) facing the magnetic field Direction judgment: The positive and negative poles of the induced electromotive force can be determined by the direction of the induced current. The direction of the current inside the power supply: flows from the negative pole to the positive pole. Induced electromotive force In order for there to be current in a closed circuit, there must be a power supply in the circuit, because the current is caused by the electromotive force of the power supply. In the phenomenon of electromagnetic induction, since there is an induced current in a closed circuit, there must also be an electromotive force in this circuit. The electromotive force generated in the phenomenon of electromagnetic induction is called induced electromotive force, which is commonly represented by symbols. The types of induced electromotive force are divided into dynamic electromotive force and induced electromotive force. Kinematic electromotive force Kinetic electromotive force is the induced electromotive force generated by the conductor itself cutting the magnetic field lines in the magnetic field. Its direction is determined by the right-hand rule. Make the thumb perpendicular to the other four fingers and in the same plane as the palm. Put your right hand into the magnetic field and let the magnetic field lines perpendicularly penetrate the palm of the hand. The thumb points to the direction of movement of the conductor, and the other four fingers point to the direction of the kinetic electromotive force. The direction of the kinetic electromotive force is the same as the direction of the induced current produced. The direction of the kinetic electromotive force determined by the right-hand rule complies with the law of energy conversion and conservation. The part of the conductor that generates dynamic electromotive force and cuts the magnetic lines of force is equivalent to the power supply. Theory and practice show that when a conductor with a length moves at a speed to cut a magnetic induction line in a uniform magnetic field with a magnetic induction intensity of , and are perpendicular to each other, the magnitude of the induced electromotive force generated in the conductor is: , and the units in the formula should all use the International System of Units, that is, volts, Tesla, meters per second. When a conductor moves in a uniform magnetic field and cuts magnetic field lines at a uniform speed, regardless of whether the circuit is closed or not, the magnitude of the induced electromotive force is only proportional to the sine value of the magnetic induction intensity , the length of the conductor, the cutting speed and the angle between and , that is, Induced electromotive force The induced electromotive force is because the change in magnetic field intensity passing through the closed coil generates an eddy electric field that causes the directional movement of the current, and its direction complies with Lenz's law. The thumb of the right hand points in the opposite direction of the magnetic field change. Make a fist with four fingers. The direction of the four fingers is the direction of the induced electromotive force. The size of the induced electromotive force is related to the speed of the change of the magnetic flux passing through the closed circuit. The magnitude is: When the magnetic flux passing through an unclosed coil changes, although there is no induced current in the coil, the induced electromotive force still exists. When the conductor rod does not cut the magnetic flux lines, but there is a change in magnetic flux in the closed loop, induced current can also be generated. Significance The phenomenon of electromagnetic induction is one of the most significant discoveries in electromagnetism. It reveals the interconnection between electrical and magnetic phenomena and is of great significance to the establishment of Maxwell's electromagnetic field theory. The important significance of Faraday's law of electromagnetic induction is that on the one hand, based on the principle of electromagnetic induction, people have created generators, making large-scale production and long-distance transportation of electrical energy possible; on the other hand, electromagnetic induction phenomena are widely used in electrical technology, electronic technology, and electromagnetic measurement. Human society has since entered the electrification era. The so-called "flux rule" states that the electromotive force in a circuit is equal to the rate of change of magnetic flux passing through the circuit. It also applies when the flux does not change, either because the field changes or because the circuit moves (or both)... But in our explanation of the rule, we use two laws that belong to completely different cases: "circuit movement" and "field change". We are not aware of any other place in physics where such a simple and accurate general principle can be used to understand and analyze two different phenomena. Extended content: Electromagnetic applications Generator The electromotive force caused by Faraday's law of electromagnetic induction due to the relative motion of the circuit and the magnetic field is the fundamental phenomenon behind the generator. When a permanent magnet moves relative to an electrical conductor (and vice versa), an electromotive force is generated. If the wire is connected to an electrical load, current will flow, thus generating electrical energy, converting the energy of mechanical motion into electrical energy. For example, drum generator. Another generator that realizes this idea is the Faraday Disc Transformer The electromotive force predicted by Faraday's law is also the operating principle of the transformer. When the current in the coil changes, the changing current generates a changing magnetic field. The second wire within the scope of the magnetic field will feel the change in the magnetic field, so its own coupled magnetic flux will also change. Therefore, there will be an electromotive force in the second coil, which is called induced electromotive force or transformer electromotive force. If an electrical load is connected to both ends of the coil, current will flow. Electromagnetic flowmeter Faraday's law can be used to measure the flow of conductive liquid or plasma. Such an instrument is called an electromagnetic flowmeter.

Shrek is the same. If it weren't for the Spirit Hall and Dai Boss, you would be a time traveler for nothing.

It's fascinating to watch 😥! 1 Is the protagonist traveling through the main Douluo universe or a parallel universe? In the main universe, Tang San is the Son of Destiny, and he can turn disaster into good fortune. Travelers can only stay humble and submissive; in the parallel universe, the protagonist is the Son of Destiny, and the author is the God of Creation. Don't be timid, just do it. 2Whose side does the protagonist stand on? Shrek, Wuhun Palace, and self-contained forces all seem to have them, but they don't seem to have them either. 3What is the major system? Both the soul master system and the martial arts system are written about, but they are mixed but not refined. My feeling is: I have written about everything, I want everything, and I am not good at anything. Is the protagonist practicing the Avenue of Chaos? Made me faint

A protagonist like this has no system and no good plug-ins. It is very important to stand in a team. Gou is the most important. It doesn't matter if you join the protagonist group, but don't worship the master as your teacher. It can develop into a relationship between a teacher and a student in the academy.

Generally speaking, when it comes to Douluo fans, I still prefer to watch the group. After all, it is a childhood memory, and I naturally have feelings for the original protagonist group. There are definitely many readers like me who love watching group tours. Since I like to read group stories, many authors now deliberately go in the opposite direction and write articles that are hostile to the protagonist group, so naturally I don't like to read them. As a reader, I recognize the diversity of fan fiction and respect the choices of authors and readers of this type of fan fiction, but I definitely don't like reading it myself because it always gives me a sense of villain that I can't replace. But even I can't stand most of the group tours now. The reasons are as follows: (1) It is too close to the original work and loses the meaning of reading fan fiction. To write a group article that satisfies us, we need to follow the group while also writing new ideas. There are too few people who can do this now. The author's originality is too low and he can only reproduce the plot of the original work. And what did the author of this book add? It seems there is, but it seems there isn't. For example, there are side plots such as catching a group of soul masters on the way to Shrek. Hope to add more. (2) The characterization is very embarrassing. First of all, San Shao himself was not perfect when creating the characters (high emotional intelligence). He was OOC in the original work, so it seemed that some of the character creations were failed and even annoying. For example, the master was fine when he was a child, but as he grows up, he becomes more and more wrong. His image as a theorist and wise man, and Bibi Dong's image of tragic love, are not established, and he seems very useless and a scumbag. This should not be blamed on the master himself, this pot definitely belongs to the third young master. This requires the fan author to eliminate the OOC content in the original work and make slight modifications. Oh, there is no problem with the original work, but the fanfic is obscene and OOC for the sake of obscenity. The hardest hit area - female characters. For example, there is an LSP author who wants to bring two beauties, Ning and Zhu, into his room at the same time. Sorry, this is extremely poisonous. Because they will not accept their men having other women! If you want more girls, please create your own. After talking about the characters of the original work, let's talk about the protagonist of the same work. I'm thinking that the intersection of fan fiction and original characters may be a shackle for the author to a certain extent - it is of course difficult to change the plot of the original work and abruptly add a new character while making the new character's image "stand-alone" without being able to make the original character's OOC (and even accurately distinguish and eliminate the OOC written by San Shao himself). I would like to talk about three points on how to integrate the fan protagonist into the original protagonist group. 1. No licking. This means don't be too flattering. It's not that you can't give them benefits, but you have to be worthy of the reward. Emotion is a two-way process. As for the clichéd problem of "licking the master"... I thought of a few ways to deal with it. ① When I traveled back in time, I was already with the master (for example, the orphan adopted by the master or something), so I can only accept the fait accompli, since it was not the protagonist's request anyway. ②The master "licks" the protagonist. In this case, wouldn't it be the other way around? Well-written writing can also make readers feel happy. Anyway, the author will stuff all kinds of weird things into the protagonist as martial arts souls. It's strange that the master is not interested. 2. No foil. The protagonist must have a unique role in the team. Don't hit the positioning! In terms of combat, anything can be done, including strong attack, auxiliary control, defense, and agility attacks. But when it comes to team matters, it's best to be the soul figure and have special skills that other companions (especially Tang San) don't have. It's a time traveler anyway, just mess with it and you'll have it. For example, someone can make concealed weapons, and the firearm you make is stronger than his concealed weapon. 3. Don't steal the show. The initial thought of readers who are willing to read the group flow is "If I were one of them, what interesting stories would there be?". And if the author writes that the combat power has expanded, surpassing the large army by too much, and all the scenes have been robbed, what's the point? Why don't you read the Lone Wolf article? It is best for the protagonist to be the first in strength in the group (but not too much) or the second in strength. (3) The author's indecision. When the author starts to write about the group flow, he must make it clear that the target audience is "the original work party who is willing to watch the group flow", not the "anti-original work party who opposes the original protagonist group"! They have a lot of books to read that suit their tastes, and you just let them go as soon as you said you wanted to join the group. Then I will write more content that the original author likes, it will be original and daily, I will regret changing the original work, the characters will not be OOC, and the plot will be more interesting. If the original author cannot find a good book, I will be willing to come. Some authors just want this and that, and they do a cool trick of "temporarily making friends during college and becoming enemies after graduation." I forgot which book it is. If you like the relationship between the protagonist and the seven monsters, you will leave immediately after reading this sentence. Those who hate the Seven Monsters might like to watch the second half, but I think half of them can tolerate the plot of Friendship with the Seven Monsters until it breaks down in the middle. But the problem is, if the protagonist is forced to break up with his teenage friend, and they also have to have a life-and-death vendetta on the battlefield, are you sure this is a fun plot and not a plot that abuses the protagonist? The anti-originalists also want to read Shuangwen, okay? How satisfying is it to watch you kill your former teachers, classmates, and comrades one by one? I can only wish him good luck. Also, the author of this book didn't even think about the outline. He didn't have any endings for the original characters, and he even asked readers to vote! The protagonist has obviously joined Shrek, and they get along so well with each other, yet they still have to choose "Should the protagonist break up with them in the future"? You don't regard the protagonist's feelings as feelings, right? On this emotional basis, if you forcibly arrange a breakup plot, you are abusing the protagonist! What else should I choose, "Should I give the Master a good ending?" Does this require a vote? You follow the group trend, but the original character in the main group who had a happy ending was killed by a knife. Who are you writing for? Ask yourself and put yourself in his shoes. Among those who like to watch tour groups, who would like to watch the plot of a master dying with a sword? It's a no-brainer for all the questions to be voted on by readers, and I'm really convinced. Looking through the book review area again, in November, the author said, "If you want to read the story about the master of torture and killing Tang San, please go away, otherwise it will make you uncomfortable and I will feel uncomfortable." This answer made the other party, an "anti-originalist", very satisfied. On December 26th, an "anti-originalist party" came and posted a message saying that he hoped that all the masters would betray their relatives and die soon. Why did you just reply "Haha, it will happen, take your time"? You've changed so quickly in the past month. Is it because there are so many anti-originalists putting pressure on you that you don't even understand the true audience of this book? The real audience of this book is destined to not be them from the first time you write "following the group" in the introduction. Why should we refer to their opinions? Just take your time, they won't see it at all.

In my book, the master is paranoid, Tang San lacks love, Xiao Wu is painful, Fatty is funny, Oscar is sad, Dai Mubai is aimless, Zhu Zhuqing is cute, Ning Rongrong is bold, Qian Renxue is not recognized, Zhao Wuji is a fool, Flanders is a tragedy, Liu Erlong is a joke, and Qian Dong is lonely. I have a showdown. In fact, the protagonist's mother Zhong Danxue is the real protagonist!

My Qian Renxue!

As soon as I found out, I asked the protagonist in the later stage whether he would kill Tang San and unify Douluo? The most disgusting character in Douluo is Tang San, and Yu Xiaogang ranks second.

I hope the masters will betray each other and kill him quickly. It looks disgusting.

Author, I haven't looked back yet, but I want to remind you that there is no such thing as absorbing soul power in Douluo's worldview. From the beginning, it is all about refining one's own soul power. Is this why? The skills Tang San learned in his previous life can be used in the Douluo world, but the rules of the world are different, and even external energy does not even exist in the outside world, except for special places like the Ice and Fire Eyes. The world of Douluo belongs to the world of high martial arts from the beginning, but it is written in a fantasy way

I want to point out what I wrote wrong, and we can discuss whether to revise it. Because I follow the team, there may be a little less people I like. Therefore, I will appropriately change the characters of the characters in the book to make them consistent with the core values ​​of socialism. Thank you (^～^).

Ma Hongjun is not considered an evil spirit master before he eats the fairy grass. . .

The writing is not bad. Sometimes I feel that the protagonist is like a child 😒, but come on＾0＾~, I voted for the November monthly vote

The author even disbanded the QQ group

After reading so many Douluo fanfics, I feel that there is not much difference between joining the Spirit Hall and Shrek. First of all, Douluo Continent really depends on luck and talent. There are really very few things that can be cheated and upgraded. Except for the fairy grass of the Ice and Fire Eyes, I really can't think of anything else. The resources that the Soul Palace can provide are actually not much, it's just There seems to be no level division or difference in the mimetic training environment, medicinal baths, and meditation methods to improve soul power in the original work. These things are basically provided by high-level academies, so there is really no special advantage in joining the Spirit Hall. The Douluo Continent is really not as advanced as the famous sects in the traditional martial arts world. They rely too much on the soul skills given by the soul ring. The self-created soul skills are naive and are not suitable for individuals or the same type of martial arts. Personal martial arts have different training experiences and are not suitable. So there is really no need to insist on going to the Spirit Hall or Shrek Academy. If you are talented, you will be popular everywhere, but if you are not talented, you will be useless.

Douluo likes Qian Renxue the most, but doesn't like Bibi Dong. She has always felt that Bibi Dong has serious mental problems and is a lunatic. Qian Renxue was deceived by her.

By the way, has the author considered who to help in the decisive battle? It was impossible for Tang San and Wuhun Palace to mediate, especially after the soul hunting operation, it was completely life-and-death. If you want to help the protagonist group, your wife and mother-in-law will be on the opposite side, and if the Wuhun Palace is gone, the evil soul masters will have no one to control them. The original book mentions that the 10,000 years after the destruction of the Wuhun Palace will basically be a dark age for the common people. After the evil soul masters were left ungovernable, the Holy Spirit Cult emerged, and unification is the general trend, and there is no force more suitable for unification than the Wuhun Palace. To help Wuhundian, the current relationship with the protagonist group and Teacher Shrek, as well as the friendship that can be said to be fatal, cannot be given up at all. What about the other parents and grandparents? Three words cannot be brought to the God Realm, and if they are left alone in Douluo Continent, they will be criticized again. ps. I only read half of it and if there is something wrong, please help to correct it.

It's rare to find a fellow Douluo who has such an appetite, don't be a eunuch! ! It's a ball😭😭

I can't hold on any longer, brothers.

I found the book yesterday. Although there are some problems in the front, the pace is very comfortable. But when I read the two chapters about going to the old poison medicine garden, I suddenly let myself go. The first two sentences were still saying not to destroy the medicine, and then the protagonist suddenly released his martial spirit like a lunatic and destroyed half of the garden of less than high-grade herbs. Suddenly, he felt a mouthful of old blood clogged in his heart. Then the protagonist almost fainted after absorbing the soul ring. Lao Dufu and Qian Renxue suddenly had the wisdom to ask the protagonist to look at the color of the soul ring. Delete these two short paragraphs. These two paragraphs do not affect the plot, but these two paragraphs really affect the viewing experience. I'll go slow first...

Whether it is original or a fan, if it is wonderfully written, there will definitely be people who will read it. Although the author did not beat the master severely, destroying Tang San was another step-by-step process. He had already changed their disgusting characters over time, so why did he still kill them to satisfy his bad taste? Come on, author, don't cut it.

It's a bit hard to understand why Douluo fan fiction is so hostile to the Master. What the Master is more criticized for is his treatment of relationships! But it can't be said that it's all the master's problem. After all, it was Bibi Dong who proposed the breakup first. Nowadays, if a girl proposes a breakup, you can't refuse it. The difference in their identities means that this relationship is very fragile and cannot bear any twists and turns.

The slow update is not such a slow method, right?

It's no fun, man, slip away

Good guy, I have always regarded the male protagonist as a clever guy 😥

I really like the author's serious and sophisticated writing style. I have just graduated from high school and am studying science, so I am always very serious when reading books. However, the author really gave me a big surprise, especially the solid foundation of physics. It makes me, a science student, very comfortable reading it. The main thing is that I can have some thinking points. It seems like I have returned to the time when I was a freshman and sophomore in high school. I really appreciate the author.

I haven't read it yet, but I found that the author's comment group is very harmonious and the author often shows up. 😰😰😰

I have read more than 40 chapters and I like it very much. There are some little jokes but not all of them are jokes. I just don't know how the protagonist will find a girlfriend later. I am going to kill it and I will not read pirated copies. I hope the author can keep writing.

Author: I'm a little confused about how old the protagonist is now.

I feel like it doesn't look good after adding the protagonists of other fan fictions.
