Moving magnet actuator

A moving magnet actuator is a type of electromagnetic linear actuator.[1] It typically consists of an arrangement of a permanent magnet and coil, arranged so that currents in the coil generate a pair of equal and opposite forces between the coil and magnet. The main difference between this and a voice coil actuator is that in a moving magnet actuator, the magnet is intended to move and the coil to stay still, as opposed to vice versa.
