solenoid

so·le·noid  (sl-noid) n. 1. A current-carrying coil of wire that acts like a magnet when a current passes through it. 2. An assembly used as a switch, consisting of a coil and a metal core free to slide along the coil axis under the influence of the magnetic field. [French solénoïde, from Greek slnoeids, pipe-shaped : sln, pipe + -oeids, -oid.] sole·noidal (-noidl) adj. sole·noidal·ly adv.

n

1. (Electronics) a coil of wire, usually cylindrical, in which a magnetic field is set up by passing a current through it

2. (Electronics) a coil of wire, partially surrounding an iron core, that is made to move inside the coil by the magnetic field set up by a current: used to convert electrical to mechanical energy, as in the operation of a switch

3. (Engineering / Automotive Engineering) such a device used as a relay, as in a motor vehicle for connecting the battery directly to the starter motor when activated by the ignition switch
