Magnet

Speakers and microphones: Most speakers employ a permanent magnet and a current-carrying coil to convert electric energy (the signal) into mechanical energy (movement that creates the sound). The coil is wrapped around a bobbin attached to the speaker cone and carries the signal as changing current that interacts with the field of the permanent

(PDF) Permanent Magnet Generator Designing Guidelines

The development of neodymium-iron-boron and samarium-cobalt magnets has made it possible to use permanent magnets even in large size motor and generator applications. Often a permanent magnet synchronous generator (PMSG) is vector controlled and indirectly connected to the network via power electronic converters.
