Most electromagnetic actuators are rotating motors, or some variation on the theme, like servos. However, it’s possible to do linear actuation with electomagnetics, too. [Adrian Perez ...

However, one of the major challenges in miniaturizing robots has been the problem of shrinking conventional electromagnetic actuators, which transform electrical energy into mechanical energy and ...

That force is produced by an electromagnetic actuator. [Grady] scratch-built his watt-balance from wood, however, even though he carefully turned and wound his own coils for the electromagnets ...
