Solenoid

A solenoid is a loop of wire, often wrapped around a metallic core, which produces a magnetic field through electromagnetic induction when an electrical current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets.

In engineering, the term solenoid may also refer to some transducer devices that convert energy into linear momentum. Three common types of solenoids are electromechanical solenoids, which harness electrical energy; pneumatic solenoids, which derive their energy from compressed air and hydraulic solenoids, which obtain energy from pressurized fluids.
