The two coins were circulated in everyone's hands for a week, and finally fell into Zixuan's hands.

Zixuan played with the coins repeatedly, and when Qianyang was still feeling sorry for herself, she suddenly asked, "Senior Sister Qianyang, in addition to using coins, have you tried other ...... The medium doesn't have it?"

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

"No, you're mistaken, I don't mean the kind 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 moment, "Tiehuan? I don't have any impression, I may or may not have tried it, what's wrong?"

"Because electricity and magnetism are inseparable, maybe you can try it in electricity. Zixuan said.

Qianyang sighed slightly, "Do you mean using magnetism to generate electricity? I've tried this, cutting magnetic fields with metal and the like, it's okay, but it's too complicated, it's still not practical, and the current generated is not strong." ”

"No, I'm saying that the essence of your ability may not be magnetism, but electricity! After all, the magnetic field and the electric field are the same kind of field, and the magnetic field is a relativistic correction of the electric field. Zixuan said in a natural tone.

“......”

Those present looked at each other.

"Don't look at me, I didn't choose that, I don't know more than you. Aurora hurriedly waved her hand, "My ability is macroscopic, I don't need to study this kind of microscopic thing, and it sounds very difficult to say it, if I really have to choose, I may not even be able to write a thesis." ”

Aurora didn't choose, and of course Qianyang couldn't choose, and she was still confused when she heard it, no better than before.

"Hasn't Yiyi come back yet? Then I'll just talk about it, not necessarily right, just listen to it. Zixuan glanced in the direction of the entrance of the department, although she knew that she wouldn't be able to see it even if Chen Yiyi came back, maybe she could smell the fragrance of food?

"You know why iron is magnetic, right?" she asked.

Chio thought hard, "Tieri's ...... If the direction of the magnetic moments is chaotic, they cancel each other out and do not exhibit magnetism, but if the direction is the same, they exhibit magnetism?"

She has always thought that her ability is magnetism, and she successfully passed the exam to enter the Red Leaf Academy, and she still knows some of the characteristics of magnetism, but because she didn't show more self-motivation in school, she didn't get special attention from the teacher.

Zixuan nodded, "What you said is partially correct, but the magnetic moment generated by the spin of electrons is mainly reflected in the microscopic aspect, and the magnetic field we feel in daily life is the macroscopic magnetic field, and the macroscopic magnetic field is mainly determined by the orbital magnetic moment generated by the quantum exchange of electrons." ”

"Huh, 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 own ability was wrong.

The transcendent needs to correctly understand the principle and mode of action of his own ability in order to effectively control the ability, if Qianyang's previous perception of his own ability is wrong, then ...... Isn't the way she uses her powers more wrong than the other?

It's not just that Qianyang didn't understand, but the people present counted one by one, and they didn't understand all of them, these things are beyond the cognitive scope of high school students and even college students, they understand every word that comes out of Zixuan's mouth, but they can't understand it together......

Zixuan patiently explained: "In the most understandable terms, according to my speculation, when you touch a metal such as a coin, your ability is like a police officer directing traffic, ordering the electrons in the coin to collectively migrate in a certain direction, and exchange positions with other electrons at the quantum level, the migration of electrons produces an electric field, and the magnetic field is only an add-on, but because the coin is not a closed conductive path, it does not produce a perceptible current." ”

Qianyang seemed to understand a little, she was like being in a room, the windows of the room were pasted with a layer of window paper, she used to be content to appreciate the simple patterns of the window paper itself, but now that the window paper was about to be pierced, she vaguely realized how gorgeous the real world outside the window was, so gorgeous that it made her scalp tingle.

The more Zixuan spoke, the more reasonable she felt, "That's right, you're not a magnet, why can you touch a coin to make it magnetic? Everyone has bioelectricity on the surface of the body, and it should be the source energy that makes your bioelectricity unique, sending instructions to the electrons in the coin." It's just that your bioelectricity is obviously a handsome traffic policeman who dares not obey the traffic, but you use it as an aunt in the neighborhood committee wearing a red armband, and let it stand on the crosswalk to guide elementary school students to cross the road......"

"Hahahaha! Meow to death with laughter~" Mio laughed heartily, she didn't understand anything else, but she understood the last metaphor, because this metaphor is really vivid and interesting.

Qianyang stood in place, stunned, she repeatedly recalled Zixuan's explanation in her mind, and tried to digest it, but her foundation was not very good, and she wanted to understand all such esoteric content at once, it was obviously impossible, so she could only take her time and find an opportunity to make up for the relevant knowledge, but at least she now has the right general direction.

"Wait a minute, I'll come when I go. Xiao Sui said, turning around and running away quickly.

After a few minutes, Qianyang was still stunned, Xiaosui had already run back, she was carrying a roll of wire in her hand, and a small lamp was connected to the wire, and said, "I'm going to borrow it from logistics, Qianyang, come and try?"

She said it twice before Qian Yang came back to her senses from the outside of the spirit.

"Huh? now...... Do you want to take the test?" Qianyang's mood was very panicked, as if the teacher had just finished talking about the new formula, and he hadn't even explained the example questions, so he put down the test paper in the classroom to assess the key points of the content just mentioned, it stands to reason that students should always be left with some time to digest and prepare, and not everyone is a genius girl.

"That's right, strike while the iron is hot, it just so happens that Sister Zixuan and Aurora are here, if there is anything wrong, you can ask them for advice right away!" Xiao Sui could guess Qianyang's panicked mood, but she knew Qianyang better and knew that someone had to push Qianyang from behind, otherwise Qianyang would keep delaying.

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

Under the repeated urging of Spike, Qianyang hesitated to hold the exposed metal core of the wire, and this wire has been connected by Spike end to end, forming a closed path, followed by an electric light in the middle, and even the light strip wire is used to demonstrate the basic knowledge of circuits to the students in the lower grades.

"That'...... That one...... If I can really discharge, I won't be electrocuted to death, right?" Qianyang was terrified, she didn't want to be finally freed from Mei Yibai's snake venom, and she met so many new friends, and she was about to usher in a beautiful new life, but she was electrocuted by herself...... Such a stupid way to die, I don't even know how to write an epitaph.

Everyone was unsure, and looked at Zixuan for answers.

Zixuan frowned and said, "This...... I'm not a supernatural, but I don't think supernatural abilities are that stupid, right? But if you're worried, you can release them in small amounts?"

"How much is a small amount?" Qianyang asked worriedly, "I'm really not sure...... The ratio of force used to magnetize in the past doesn't necessarily apply now, does it?"

Seeing that she was so worried, Zixuan proposed: "Then you can try it with a voltage tester first, if my guess is correct, the voltage tester should be bright." ”

Koho ran to borrow a voltage tester again, and this time Qian Yang was more relieved, she pinched the metal end of the voltage tester with two fingers, closed her eyes and tried to understand the orbital magnetic track generated by the quantum exchange of electrons.

The others stared intently at the end of the pen, where there was a neon bubble that would light up if enough voltage was sensed. Even Miao followed everyone's example and stared at it curiously, she didn't know what everyone was waiting for, she was curious anyway.

However, after waiting for several minutes, the neon bubble never lit up, but everyone's eyes were sour.

"What the hell are you looking at, is there a bug in this pen or is it going to suddenly turn into a big mouse?" Mio cried out impatiently.

"Shhhh

Everyone can understand Qianyang's mood and pressure at this time, in front of everyone's eyes, she is more anxious than anyone else, no one knows if she can turn pressure into motivation, Xiaosui is already reflecting on whether she is pushing her too hard, and how to comfort her if she doesn't succeed.

Qianyang's forehead and nose were already sweating, and Aurora lowered the temperature around her a little, so that Qianyang could concentrate and think - with the experience of cooling the water just now, Aurora was more comfortable controlling her power and fine-tuning the temperature, although it sounded more like a mobile air conditioner, but everyone understood that she was providing convenience for Qianyang, and no one would laugh at her as presumptuously as Layla.

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

It is not difficult to use 100 points if you have 100 points of ability, but it is not so simple to use only one point accurately with 100 points of ability, just like a muscular man carving a tofu block with a scalpel.

The air temperature decreased, and Chio's body and mood calmed down a little at the same time.

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

After a while, Jiang Chanji noticed that Chen Yiyi came back with two large shopping bags in each hand, the shopping bags were full of all kinds of food, she was struggling to carry, and the straps of the shopping bags looked like they might break at any time, so he hurriedly walked a few steps to pick her up, first made a shushing gesture, and then took the shopping bag from her hand.

In fact, Chen Yiyi didn't talk much, and he could observe words and feelings, not as reckless as Mio, seeing this situation, even if he didn't remind him, he wouldn't be silent.

Chen Yiyi really bought a big bag of fast food, fried chicken, fries, hamburgers, chocolate pies and the like, which happened to his appetite, while the other bag was some snacks that girls liked. She returned the black card to No. 33 and watched quietly.

Zixuan smelled the hot aroma of fried chicken and couldn't stop swallowing her saliva, but she didn't want to disturb Qianyang, she endured the hunger in her stomach, and just hoped that Qianyang would succeed soon.

After waiting for another ten minutes, Xiao Sui saw that the time was not far from the end of the lunch break, and she couldn't wait indefinitely, and was about to step forward to interrupt Qianyang, when she just took a step forward and wanted to speak, she saw the neon bubble of the electric tester flash, and then extinguished.

She was stunned for a moment, thinking that she had seen it wrong, or mistaken the reflection of the sun, and quickly looked at the expressions of others, only to see that everyone was surprised and surprised, which confirmed that Qianyang really succeeded, and also proved that Zixuan was right, Qianyang's ability is not magnetic, but electricity, because Qianyang's hand holding the voltage tester was motionless, and there was no action to cut the magnetic inductance line, so this is not due to magnetism - on the contrary, the so-called magnetization ability of Qianyang in the past is due to electricity.

"Congratulations, Qianyang!

Xiao Sui happily pounced and wanted to give Chio a hug, but Chio avoided him.

"Wait, wait, wait, I'm afraid that if I get excited and use my ability, if I get electrified of you, I'll have to regret it!" Qianyang hurriedly waved his hand.

"Haha, Chio is very cautious, but it doesn't matter, your electric pen has been extinguished. Spike laughed.

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

"Huh?" Kosui was puzzled.

Zixuan stared at the neon bubble at the back end of the voltage tester and said, "It only flashed for a moment, which means that it was only energized for a moment, and there are two explanations for this, either it is extinguished, or it is ...... Is it the excessive voltage that burned the neon bubbles! For the first time, Senpai Chio learned to use her abilities correctly, so she could send and receive them so freely and only power on for a moment?"

"Uh......"

Everyone was stunned, and Xiao Sui asked on behalf of everyone, "The voltage is too high...... How old is it?"

"This is a low-voltage voltage tester for teaching experiments, right? It stands to reason that the upper limit is 500 volts, and if you exceed this voltage, you will destroy the neon bubble. Zixuan replied.

500 volts?

It sounds dangerous, but 220 volts of mains electricity can electrocute people.

"Qianyang, how long did you use the ability just now?" asked, Koho.

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

"Was it a moment?" asked.

"Anyway, all of a sudden, I saw the light on, and my heart was relieved, as if I had withdrawn my ability...... But I'm not sure either. Qianyang shook his head and said, "It's hard for me to say how long it will be." ”
