一、电磁驱动小车装置图(如图1所示)二、特点及用途1.特点通过小车的实际运动来说明通电导体受到安培力作用,与实际的电磁驱动列车相比较,让学生深切感受到物理与生活的紧密联系。2.电磁驱动小车的用途(1)在导轨上通电后,观察到小车运动,说明小车受到安培力作用;(2)改变电流大小,观察到小车运动快慢变化,说 First, the electromagnetic drive car device diagram (as shown in Figure 1) Second, the characteristics and uses 1. Features Through the actual movement of the car to illustrate the power of the conductor by Ampere force, compared with the actual electromagnetic drive train, so that students feel deeply The close connection between physics and life. 2. The use of electromagnetic drive car (1) on the rail after power, the car was observed movement, indicating that the car by the Ampere force; (2) change the current size, observed changes in the speed of the car, that
