Chapter 301 True Ability

The two coins were passed around for a week, and finally fell into Zixuan's hands.

Zixuan repeatedly played with coins, and when Qianyang was still complaining about herself, she suddenly asked, "Senior Qianyang, besides using coins, have you tried other... mediums?"

"I've tried it." Qianyang nodded, "I've tried all kinds of metals, such as gold, silver, copper and iron, except metals that don't exist on the earth, or metals that can't be touched directly with hands, such as lithium or radium. , I’ve tried it all, I’ve tried it at home, I’ve tried it at school.”

"No, you misunderstood, I didn't mean the type of metal." Zixuan shook her head and corrected: "I mean the shape and size, especially the closed metal, such as the iron ring."

Qianyang thought for a while, "Iron ring? I don't have any impression, maybe I tried it or maybe I haven't tried it, what's wrong?"

"Because electricity and magnetism are not separate, maybe you can try electricity." Zixuan said.

Qianyang sighed slightly, "Does it mean to use magnetism to generate electricity? I have tried this. It is OK to use metal to cut the magnetic field, but it is too complicated, and it is still of no practical value, and the current generated is not strong. .”

"No, I mean that the essence of your ability may not be magnetism, but electricity! After all, the magnetic field and the electric field are the same field, and the magnetic field is the relativity correction of the electric field. You only need to take quantum field theory to know this." Zixuan said in a natural tone.

"..."

Those present looked at each other in blank dismay.

"Don't look at me, I didn't choose that one, and I don't know more than you." Aurora quickly waved her hand, "My ability is macro-oriented, and I don't need to study such micro-oriented things. Besides, it sounds very difficult. If you really want to If you choose, you may not even be able to write a thesis.”

Aurora didn't choose, and Qianyang is of course even more unlikely to choose, and she is still confused, not better than before.

"Has Yiyi not come back yet? Then I'll just talk about it casually, it's not necessarily true, you just listen." Zixuan glanced in the direction of the entrance of the department, although she knew that she would not be able to see Chen Yiyi even if she came back, But maybe you can smell the food?

"Why does iron generate magnetism, you always know this?" She asked Qianyang.

Qian Yang tried hard to think about it, "In the iron... the magnetic moments formed by the electron spins? If the directions of the magnetic moments are chaotic, they will cancel each other out and will not show magnetism, but if the directions are the same, they will show magnetism?"

She has always believed that her ability is magnetism, so she successfully passed the exam and entered Hongye Academy. She still understands some of the characteristics of magnetism, but because she did not show more self-motivated in school, she did not get special attention from the teacher .

Zixuan nodded, "What you said is partly correct, but the magnetic moment generated by the electron spin is mainly reflected in the microscopic level, while the magnetic field we feel in our daily life is the macroscopic magnetic field, and the macroscopic magnetic field is mainly determined by the quantum exchange of electrons. The orbital magnetic moment generated by the action."

"Ah? Is that so?"

Qianyang was stunned, she didn't understand much, but at least she understood that if what Zixuan said was correct, it meant that her previous perception of her abilities was wrong.

Extraordinary people need to correctly understand the principle and function of their own abilities before they can effectively control their abilities. If Qianyang's previous understanding of her abilities was wrong, then... wouldn't her way of using her abilities add to her mistakes? ?
Not only Qianyang didn't understand, but everyone present didn't understand. These things are beyond the cognition of high school students and even college students. They understand every word Zixuan said, but together I can't understand it together...

Zixuan patiently explained: "In the most easy-to-understand terms, according to my guess, when you touch a metal like a coin, your ability is like a policeman directing traffic, ordering the electronic collective in the coin to Migrating in a certain direction, exchange positions on the quantum level with other electrons, the migration of electrons generates an electric field, the magnetic field is just an additional product, but because the coin is not a closed conductive path, there is no appreciable current."

Qianyang seems to understand a little bit, she is like being in a room with a layer of window paper pasted on the windows, she used to be satisfied with admiring the simple pattern of the window paper itself, but now the window paper is about to be pierced, she It was only then that she vaguely realized how gorgeous the real world outside the window was, so gorgeous that it made her scalp tingle.

The more Zixuan talked, the more she felt that it made sense, "Is that right? You are not a magnet. Why do you make the coin magnetic when you touch it? Everyone has bioelectricity on the surface of the human body. It should be the source that makes your bioelectricity They are different, and issued instructions to the electrons in the coin. However, your bioelectricity is obviously a handsome traffic policeman who orders traffic to follow, but you use it as a neighborhood committee lady wearing a red armband, let it stand Leading schoolchildren to cross the road at a pedestrian crossing..."

"Hahahaha! I'm so laughing~" Mio burst into laughter. She didn't understand anything else, but she understood the last metaphor, because this metaphor is both vivid and interesting.

Qianyang stood there blankly, dazed in a daze. She revisited Zixuan's explanation repeatedly in her mind and tried to digest it, but her foundation was not very good. It was obviously impossible for her to understand such a profound content all at once. She can only take her time and look for opportunities to catch up on relevant knowledge, but at least she has the right general direction now.

"Wait a minute, I'll come as soon as I go." Xiaosui said, turning around and running away quickly.

Within a few minutes, Qianyang was still dazed, and Xiaosui had already run back, holding a roll of wires in her hand, with a small light attached to the wire, and said: "I'll borrow it from the logistics, Qianyang, come here. try?"

She said it twice before Qianyang came back from his mind wandering.

"Ah? Now...going to try?" Qianyang was in a panic, as if the teacher had just finished explaining the new formula, and even before explaining the sample questions, he put down the test paper in class to assess the key points of the content just said. Yes, it stands to reason that students should be given some time to digest and prepare, and not everyone is a genius girl.

"That's right, let's strike while the iron is hot. Sister Zixuan and Aurora are both here. If there is anything wrong, I can ask them for advice immediately!" Xiaosui could guess Qianyang's flustered mood, but she knew Qianyang better , Knowing that someone must push Qianyang from behind, otherwise Qianyang will keep procrastinating.

"I can't help much, and I'm also a bystander." Aurora didn't use Zixuan to elevate herself.

Under Xiaosui's repeated urging, Qianyang hesitated to hold a section of the exposed metal core of the wire, and this piece of wire had been connected end to end by Xiaosui to form a closed path, with an electric light in the middle, and even the light wires were connected. It is a teaching material used to demonstrate the basic knowledge of circuits to students in the lower grades.

"Then... that... If I can really discharge electricity, I won't electrocute myself, right?" Qian Yang was terrified, she didn't want to finally get rid of Mei Yibai's snake venom, and meet so many new friends , is about to usher in a wonderful new life, but he was electrocuted to death by himself... Such a stupid way to die, I don't even know how to write the epitaph.

Everyone was unsure, and looked to Zixuan for answers.

Zixuan frowned and said, "Well... I'm not a superhuman, but I don't think superhuman abilities are that stupid, right? But if you're worried, can you release a small amount of power?"

"How much is a small amount?" Qianyang asked anxiously: "I'm really not sure... The ratio of power used to magnetize in the past may not be applicable to the present, right?"

Seeing that she was so worried, Zixuan suggested: "Then you can try it with a tester first. If my guess is correct, the tester should light up."

Xiaosui went to borrow another electric probe, and now Qianyang was more at ease. She pinched the metal end of the electric probe with two fingers, closed her eyes, and tried to understand the orbital magnetic track produced by the quantum exchange of electrons. .

Others stared intently at the end of the pencil, where a neon bulb lit up if enough voltage was sensed.Even Mio followed everyone's example and stared there curiously, she didn't know what everyone was waiting for, she was curious anyway.

However, after waiting for several minutes, the neon bulbs did not light up, and everyone's eyes were sore.

"What are you looking at? Is there a bug in this pen or will it suddenly turn into a big mouse?" Mio cried impatiently.

"Hush! If you don't want to wait, go play by yourself and don't disturb others!" Jiang Chanji pushed her back and pushed her aside, but the more this happened, the more curious Mi Ao became.

Everyone can understand Qianyang's mood and the pressure she is facing at this time. Under the watchful eyes of everyone, she is more anxious than anyone else. No one knows whether she can turn the pressure into motivation. Xiaosui is already reflecting on whether she has forced her to too tight, and how to comfort her if she doesn't succeed.

Qianyang's forehead and nose were already sweating, and Aurora slightly lowered the surrounding temperature, so that Qianyang could concentrate on thinking—with the experience of cooling water just now, Aurora was more comfortable controlling her own power and fine-tuning the temperature. Although it sounds more like a mobile air conditioner, everyone understands that she is providing convenience for Chiyang, and no one will laugh at her as freely as Leila.

Today's experiment has also benefited Aurora a lot. In order to get rid of the nickname of the mobile air conditioner, she used her full power almost every time she used her abilities, and the temperature dropped as fast as she could. The use of abilities was too rough and not enough. Delicate, but today she seems to vaguely understand a word - lifting weights like light.

It is not difficult to use one hundred points with one hundred points of ability, but it is precisely one point with one hundred points of ability, just like a muscular man carving patterns on a block of tofu with a scalpel, But it's not that simple.

The temperature of the air dropped, and Qianyang's body and mood became slightly calmer at the same time.

It's not that she is stupid, it's just that it is too difficult to understand the quantum exchange of electrons and imagine the microscopic and abstract concept of electron's orbital magnetic moment in a hurry.

After a while, Jiang Chanji noticed that Chen Yiyi came back with two big shopping bags in each hand. The shopping bags were full of all kinds of food. So he quickly walked a few steps to pick her up, first made a boo gesture, and then took the shopping bag from her hand.

In fact, Chen Yiyi didn't talk much at first, and he was able to observe words and expressions, unlike Mi Ao who was so reckless, seeing this situation, even if he didn't remind him, he would not say a word.

Chen Yiyi really bought a big bag of fast food, such as fried chicken, french fries, hamburger and chocolate pie, which was just right for him, and the other bag contained some snacks that girls like.She returned the black card to No. 33 and watched quietly.

Zixuan could not stop swallowing when she smelled the hot fried chicken, but she didn't want to disturb Qianyang, so she suppressed the hunger in her stomach, and only hoped that Qianyang would succeed soon.

After waiting for another ten minutes, Xiaosui saw that the time was not far from the end of the lunch break, and she couldn't wait indefinitely, so she was about to step forward to interrupt Qianyang. Flashes, then goes off again.

She was stunned for a moment, thinking that she had misread, or misunderstood the reflection of the sun, and quickly looked at the expressions of other people, only to see that everyone was both surprised and surprised, which confirmed that Qianyang really succeeded, and also proved Zixuan That's right, Qianyang's ability is not magnetism, but electricity, because Qianyang's hand holding the electric test pen is motionless, and there is no action of cutting the magnetic field line, so this is not electricity due to magnetism—on the contrary In the past, Qianyang's so-called magnetization ability was magnetism caused by electricity.

"Congratulations, Qianyang! You made it!"

Xiaosui jumped over happily, wanting to give Qianyang a hug, but Qianyang avoided her.

"Wait, wait! I'm afraid that if I get excited and use my abilities again, if I shock you, I will regret it to death!" Qian Yang waved her hands quickly.

"Haha, Qianyang is very cautious, but it doesn't matter, your electric pen is already off." Xiaosui laughed.

"Are you sure it's gone?" Zixuan said in a suspicious tone.

"Huh?" Xiaosui was puzzled.

Zixuan stared at the neon bulb on the back of the test pen, and said, "It only flashed once, which means it was only powered on for a moment. There are two explanations for this, either it went out, or... the neon bulb was burned due to excessive voltage. Ah! The first time Qianyang-senpai learns to use the ability correctly, can she send and receive the power so freely for only a moment?"

"Uh……"

Everyone was stunned, and Xiaosui asked on behalf of everyone: "The voltage is too high... how big is it?"

"This is a low-voltage testing pencil for teaching experiments, right? It stands to reason that the upper limit is 500 volts. If the voltage exceeds this level, the neon bulb will be destroyed." Zixuan replied.

500 volts?
It sounds very dangerous. 220 volts of mains electricity can kill people.

"Qianyang, how long did you use your ability just now?" Xiaosui asked.

"Uh... I... I didn't pay attention..." Qianyang stammered, she was too excited just now, she really didn't pay attention to the time.

"Is it for an instant?" Xiaosui asked.

"Anyway, it was all of a sudden. When I saw the light turned on, I felt relieved, as if I lost my ability...but I'm not sure." Qian Yang shook her head and said, "I really can't say how long it will be all of a sudden."
