Solenoids
Solenoids are electromechanical devices. A typical solenoid con-
sists of a coil of wire that has a metal plunger through its center.
When energized, the coil creates a magnetic field that either pulls
or pushes the metal plunger (see Fig. 4.6). The metal plunger is
mechanically connected to the robotic device that needs movement.
