sol·e·noid

(sol'ĕ-noyd),
A helical coil of wire energized electrically to produce a magnetic field, which induces a current in any conductor placed within or near the coil.

solenoid

(sōl′lĕ-noyd)
A coil of insulated wire in which a magnetic force is created in the long axis of the coil when an electric current flows through the wire. It may be used to activate switches.
