摘要
介绍了一种自制的电磁感应演示仪.该演示仪利用同性相斥的原理,缓冲并助推了磁铁的往复运动,通过发光二极管可以直观并持续地展示电磁感应现象.该演示仪结构简单,便于携带和操作.
A kind of instrument is designed for demonstrating electromagnetic induction, which is easy to carry and operate. The reciprocation of magnet is buffered and boosted by the same poles fixed on the instrument. The phenomenon of electromagnetic induction is shown continuously and intuitively by light-emitting diodes.
