Electricity generator with permanent magnet inductor - has magnetic ball moving around inside hollow plastics torus with coil wound around it

摘要

The generator of electricity consists of a hollow torus (2) made of injection moulded plastics. The system includes a magnetic ball (1) which is free to move around the inside of the torus. An iron sleeve is placed over part of the torus and there is a coil (3) which is around its outside. Several coils and several sleeves may be employed. If more than one magnetic ball is used then they are separated by nonmagnetic balls. There may be only one coil (3) or more than one coil.
