SOLENOID

An electrically operated magnetic device used to operate some unit. A movable iron core is placed inside a coil of wire which moves because of magnetic attraction when electric current is fed to the coil . When current flows through the coil , the core will attempt to center itself in the coil. In so doing, the core will exert considerable force on anything it is connected to. Also see clutch solenoid , idle stop solenoid , and starter solenoid .
