Chapter 47 It's Broken
Arthur looked at Faraday who was standing in front of him, and felt the other's kind and gentle attitude, and that familiar face.

Arthur was silent for a while, and suddenly felt that it might be better to see him in the textbook.

Even though Arthur thinks his physics is not bad, his memory is still in the relatively excellent range.

But what if, if he misremembered the theorem, wouldn't he be infamous forever?

Seeing that Arthur hadn't spoken for a long time, Faraday thought that his sudden arrival had attracted too much attention from the audience, which frightened the science-loving Scotland Yard police officer.

At the Royal Society, Faraday often encountered scientists who did not like the limelight.

Therefore, he took Arthur as their kind for granted.

Faraday bowed embarrassedly to express his apology: "Mr. Police Officer, I didn't mean to interrupt the discussion between you and your friend.

But I think the memorization method you just mentioned seems to be really suitable for helping students who are new to the field of electricity.

If you are too embarrassed to share in public, we can wait until the lecture is over to communicate slowly. "

Faraday had just finished speaking, and Arthur hadn't answered yet. Elder, who was sitting by the side, was not happy.

The boy noticed that the eyes of all the ladies in the audience were focused on the three of them. Elder, whose hormones soared to the limit, stood up with a snap, and spoke to Faraday.

"Mr. Faraday, my friend is shy and not good at talking. Just ask me if you have any questions."

Seeing that Elder was willing to volunteer, Faraday happily held his hand: "So, may I ask you, what happened to the right hand just now?"

"This is simple. This...the right hand...is...the right hand...ah..."

Maybe it was because he stood up so violently that the blood oxygen supply in Elder's body couldn't keep up, and his mind went blank. Not to mention repeating the knowledge that Arthur had said, he couldn't even speak a complete sentence.

Master Elder hesitated for a long time, but for some reason, a flash of light suddenly appeared in his mind.

He grabbed Faraday's right hand and brought it close to his eyes. After studying it carefully for a long time, he opened his mouth slowly.

"Uh...Mr. Faraday, the wisdom line of your right hand..."

As soon as Elder said this, bursts of bursts of laughter erupted in the venue, and the air was filled with a cheerful atmosphere.

The reserved ladies covered their mouths with fans, their eyes narrowed into a line of laughter.

As for the men, they were not so particular. They were out of breath from laughing, and they were holding their stomachs and couldn't straighten up.

And the gentleman who graduated from Cambridge who sat behind Arthur laughed and patted the back of the chair, and he shouted intermittently.

"No...that's right. They...their Oxford education is like this."

Seeing this, Arthur couldn't help covering his face with one hand: "Elder, if you don't know it, you don't know it. What can you do?"

Elder's face turned pale, his brow was sweating with guilt, and he cursed in a low voice: "Arthur, Arthur! You fucking save me!"

Things have developed to this point, even if Arthur doesn't want to come out, he can't do it.

He stood up and explained, "Mr. Faraday, I..."

Faraday was also a little overwhelmed by the antics made by Elder. When he saw Arthur standing up, his first reaction was to ask hesitantly, "Would you like to help me again?" Fate line?"

Before Arthur could speak, Elder, who was eager to get rid of the embarrassment, rushed to speak again: "Mr. Faraday, you don't need to bother Arthur with such trivial matters. I have already read them all for you, and your fate line is also very good."

Now, the laughter in the venue can be used for a concert.

Arthur, who has always been good-tempered, finally couldn't help but glared at Elder when he heard this, and muttered to him in a low voice.

"What's the matter with you here? Shut up!"

Elder quickly stopped talking, and he also knew that if he said a few more words, his reputation in the Royal Society lecture hall would be completely ruined from now on.

Arthur took a deep breath and quickly adjusted his mood.

He said, "Mr. Faraday, the right hand is what I use to judge the direction of electricity. Of course, you used coils in your second experiment, so you can also use..."

When Faraday heard this, he nodded and said: "Yes, the coil can be judged by Ampere's law, that is, the right-hand spiral rule. But the right-hand rule you mentioned just now seems to be different from the right-hand spiral rule."

When Arthur heard this, although he still maintained the inherent calmness and calmness of the Scotland Yard policeman, the red devil beside him had already begun to laugh uncontrollably.

"Arthur, what's the matter with you? Look at your neck, sweat is coming down. Don't you know the right-hand spiral rule? It was proposed by the Frenchman André Ampere in 1820. If you don't Yes, I can teach you. A soul, the price is fair and cheap."

But although Agares saw that Arthur was sweating, he obviously guessed wrongly what Arthur was thinking. Arthur didn't know the right-hand spiral rule, but what surprised him was—Ampere had already proposed it?
Arthur pondered for a moment, then said cautiously: "I was also inspired by Ampere's law, so I came up with the method of judging with left and right hands.

The judgment method of the right-hand rule is to make the thumb perpendicular to the other four fingers, and all of them are on the same plane as the palm.

At this time, put the right hand into the magnetic field, let the magnetic induction line pass through the palm of the hand vertically, and the thumb points to the direction of the conductor movement, then the direction pointed by the other four fingers is the direction of the induced current. "

When Faraday heard the words, he immediately stretched out his finger and gestured for himself. After a while, his frown suddenly relaxed.

He smiled happily: "It's really like this!"

As soon as Faraday said this, the laughter of the gentlemen and ladies present gradually faded away, and they all stretched out their right hands to gesture to each other.

Not long after, an uproar was heard in the venue.

"What a genius summary."

"As Mr. Faraday said, it's really good for beginners to memorize."

"And what about the left-hand rule, Mr. Inspector?"

Faraday heard that the audience had started to ask questions for him, so he didn't speak, just looked at Arthur with a smile.

Arthur also understood the meaning in Faraday's eyes, and he stretched out his left hand to demonstrate: "The left-hand rule is used in roughly the same way as the right hand, the difference is that it is used to judge power, not to judge current. .

Ladies and gentlemen, please stretch out your left hand, make your thumb perpendicular to the other four fingers, let the lines of magnetic induction flow in from your palm, and your four fingers point to the direction of current, then what your thumb points to is Ampere’s force, that is, the force on a conducting wire in a magnetic field direction.

If the moving charge is positive, the pointing of the thumb at this time can also be expressed as the direction of the Lorentz force, and if the charge is negative, the opposite direction of the thumb pointing is the direction of the Lorentz force. "

Arthur breathed a sigh of relief after saying this.

He doesn't care if he remembers it right or wrong. Anyway, if a master scientist like Faraday finds out that he is wrong, he will definitely correct it. In order to help Elder escape, he is going all out today.

Just as he was about to sit down, Arthur suddenly found that the atmosphere in the venue was not right.

The gentlemen and ladies present neither gestured with their hands as before, nor laughed loudly, but stared at him blankly one by one.

Just as Monk Arthur Zhang was puzzled, Faraday spoke.

He asked Arthur apologetically, "Forgive me for being ignorant, may I ask you a question, what is Lorenz force?"

When Arthur heard this, his pupils shrank slightly, and he thought to himself, "It's broken, something serious happened."
