Chapter 13
"Do you think I don't know if you're sitting there? Alright, now please get up and answer the question on the PPT, the girls in the sixth row." Miejue Shitai saw the two pretending, so he clicked on the girl sitting between them. Wang Yue.

Wang Yue, who was named, looked from the book to the PPT. This PPT has only one picture, and the picture reads: "Quantitative analysis of the physical principle of using the Hall effect to measure the magnetic field."

Wang Yue's voice was cold and indifferent, and he analyzed one by one: "Turning left/right, when the current passes through the conductor perpendicular to the external magnetic field, a potential difference will appear between the two end faces of the conductor perpendicular to the direction of the magnetic field and current. This phenomenon is the Hall effect. The moving electrons are affected by the electric field force and the Lorentz force, the two directions are opposite, and the Lorentz force is greater than the electric field force at the beginning, so the electrons will deflect along the direction of the Lorentz force and gradually Accumulate on the side, which makes the potential difference gradually increase until the electric field force and the Lorentz force are balanced, and the electrons are no longer deflected. Force analysis, from the electric field force formula F=qE, Lorentz force formula F=qvB, qE=qvB , so knowing E, v, the size of B can be determined."

Wang Yue's answer was perfect, and Miejue Shi, who wanted to take advantage of this lecture, coughed too lightly: "This student's answer is very standard, and this is not the reason for you to desert in class. Well, you can sit down down.

Hearing Master Miejie say that Wang Yue's answer was very standard, the students felt envious in the audience.

Student A sighed: "Scholar is worthy of being a master, you can still do it without listening in class!"

"Hey, if I had this IQ, I would have let myself go, and my parents wouldn't have to worry about it." Student B sighed.

The two looked at each other, sighed and shook their heads at the same time: "Well, let's study hard and try not to fail."

Sitting behind Wang Yue was Su Jianren, Wang Yue's number one fan of the Department of Physics: "As expected of a student master with the title of high coldness, he is so classy and I like it very much." As he spoke, he was intoxicated with himself.

Gu Ming and Yang Liu, who were sitting on both sides of Wang Yue, heard Su Jianren's words in the back row, and looked at Wang Yue's reddish ears that were faintly covered by long hair.

Superficial, vulgar.You are being blinded by appearances.

Recalling the first time I met Wang Yue, she looked straight ahead, with air-conditioning exuding from her body. Even when we came up to say hello, her eyes felt a little oppressive when she looked at us.

But when we got to know her better, we realized that she is a typical person who is cold on the outside and hot on the inside.Only very close friends and family will drop the disguise.

After school.

The three of Wang Yue walked on the school road.

There are pine trees planted on both sides of the school road, with lush branches and leaves.The ground is also covered with pine leaves blown down by the spring wind.

"You two are talking in class and you are so excited. Didn't the astronomy professor invite you here since the end of last semester?" Wang Yue despised the two of them. "How about you be a little ambitious? No matter how young the professor is, he is still in his 40s. You weren’t even born when they got married and had children!”

"Yueyue, you are wrong in saying that. Handsome men are the shared resources of the whole world. Moreover, the older the man, the more attractive he is!" Gu Ming retorted, looked around, and said quietly: "But as far as I know Well, the professor who was supposed to be invited replaced the position with his favorite student because of temporary errands. And this favorite student is said to be from the Ivy League."

Yang Liu nodded aside: "Yeah. I also heard about this from the brother in the corresponding class. Not only is he highly educated but also good-looking!" Speaking of this, his expression was a little depressed, "It's a pity that his class is not casual. You can get in."

 I love you (ω)
