The key interaction is between a permanent magnet mounted to the end of the waving arm/pendulum and a many-turn wire coil attached to the body. As the magnet swings over the coil, its movement ...

Increasing the number of turns on the coil of wire The image below illustrates a simple experiment to demonstrate electromagnetic induction. The direction of a motor effect force can be found ...

Connect one end of the coil to one terminal of the knife switch ... The mechanical energy is caused by the attractive force of the electromagnet. Now imagine a circle of electromagnets that ...
