No longer afraid of high school coil Motors(coil motors) physics problems. According to reason, girls tend to choose text when they choose high school subjects, but there is water on the head of the small editor(over-confidence in himself), and they choose reason, and they are physical and chemical. Speaking of this, it brought back a sad past of the small editor. When he wanted to divide the department that year, the small editor entered the second grade with the number of English words + physics and chemistry ranking four. However, the Lord who can not explain it, so in the next year or so, the small editor from the school tyrants to learn slag, in the face of the physical "fortress" heart.
The small editors will often encounter questions related to the coil motor(coil motor), and one question is still deeply remembered. The coil motor(coil motor) is a special motor used in hard disk, optical drive, etc.. The illustration is a schematic diagram of the principle of a coil motor(coil motor). It consists of a pair of pairs of magnetic poles and a square rigid coil. Consisting of, the coil side length is L, The number of turns is N, the magnetic induction intensity of the magnetic pole in the area is B, the direction is perpendicular to the coil plane, and the magnetic field outside the area is ignored. The left border of the coil is always outside the magnetic field, and the right border is always inside the magnetic field. The length of the front and rear borders in the magnetic field is always equal, and the current in the coil is constant to I. At some point, the speed at which the coil moves horizontally to the right is V, then at this time()
A. The induced electromotive force generated in the coil is BLv
B. The size of the Ampere force received by the coil is BIL

C. The power received by the coil is nBILv

Do you have a friend who knows the answer? Xiaobian is currently working at Kunshan Tongmao Electronics Co., Ltd.. I believe that many people have heard about the company. Tongmao is a company that specializes in the development, production, manufacture and sale of linear motors and sound loop Motors. Employees have been trained systematically. As far as the small editor knows, the ring motor(ring motor) in the above picture should be flat or rectangular.
