Abstract
Magnetic actuators are perhaps among the oldest types of actuators. They are used in everyday appliances in the form of relays, electromotors and automatic valves. Magnetic actuation methods offer the possibility of generating repulsive forces in addition to attractive forces. This is in contrast to electrostatic schemes which offer only attractive forces. In most cases, the force versus displacement relationship in these devices is also much better behaved than in coulombic electrostatic actuators.
