摘要
针对教材中洛伦兹力演示仪的不足,设计了水槽式洛伦兹力演示仪.该演示仪通过观察水槽中漂浮物运动情况判定洛伦兹力方向和大小,并探究洛伦兹力F与磁感应强度B、带电粒子q以及其运动速度v之间的关系.
Aiming at the deficiency of traditional Lorenz force demonstrator,flume type Lorenz force demonstrator was designed.The direction and strength of Lorenz force was judge by observing the flotage in the flume,and the relations between Lorenz force and magnetic field intensity,electronic charge and velocity were explored.
