Demonstrates a switched reluctance generator.
Switched reluctance generators do not have any magnets and rely on torque produced by the magnetic steel (just like a solenoid). The generators are relatively inexpensive but require complex controls. An alternative is a combination reluctance/magnet generator that uses both for torque. This kind of machine is used in the Toyota Prius.
