通电导体在磁场中受力的作用而运动,教材中安排的演示实验,只能观察到通电直导线短暂的运动过程,为便于学生观察到通电直导线在磁场中因受力而持续不停地运动的现象,
The energized conductors are moved by the force in the magnetic field. The demonstration experiment arranged in the textbook can only observe the transient motion of the energized straight conductors. In order to facilitate the students to observe that the energized straight conductors are constantly in the magnetic field due to the force. The phenomenon of sports,
