洛伦兹力是指磁场对运动电子或离子的作用力.本装置用于显示磁场对溶液中运动离子的洛伦兹力.电解质溶液中的运动离子在磁场中受洛伦兹力,带动整个液体的定向移动.本装置通过透明圆形轨道中导电液上的漂浮物的运动,展示磁场对离子洛伦兹力的大小和方向规律.1实验室演示仪的不足一般学校拥有的洛伦兹力演示器为“JY219-87洛伦兹力演示器”.它能演示电子在匀强磁场及电场作用下的运动规律,并能测定电子的荷质比.
Lorentz force refers to the magnetic field on the movement of electrons or ions force.The device is used to display the magnetic field on the movement of ions in solution Lorentz force.Electrolyte solution in the ion Lorentz force in the magnetic field, Liquid directional movement.This device through the transparent circular orbit conductive liquid floating objects on the movement, showing the magnetic field on the ion Lorentz force size and direction.1 lack of laboratory demonstrator General school owned Lorentz Force Demonstrator for the “JY219-87 Lorentz Force Demonstrator ” It can demonstrate the law of electrons in a uniform magnetic field and electric field, and can determine the charge-mass ratio of electrons.
