Definitions
Aviation
- noun a cylindrical coil of wire acting as a magnet when carrying electric current
Cars & Driving
- noun an electrically energized coil of insulated wire which produces a magnetic field within the coil, usually used to pull a movable iron core/plunger to a central position within the coil; used as an actuating device, e.g. for valves
Construction
- An electromagnetic coil used to activate a mechanical device or switch.
Electronics
- An electromechanical device which incorporates a coil wound around a movable core, and which produces a magnetic field when a current flows through it, inductively moving said core. The core is usually consists of a ferromagnetic cylindrically-shaped plunger or rod. Used, for instance, to convert electrical energy into the mechanical energy utilized to operate electromechanical devices and equipment.
- A coil which has been wound into the shape of a cylinder. When a moveable ferromagnetic core is inserted in its center, the result is a solenoid (1). Also called solenoid coil (2).
