A solenoid is device that uses the principle of an electromagnet to convert electrical current into mechanical movement. Most typically it is a coil of insulted wire, which, when electric current flows through the wire, has an induced magnetic field...

A means of converting electrical force into mechanical force. It consists of a wire coil, usually surrounding a cylindrical metal former, through which an electric current is passed to create a magnetic force. This latter is used to operate switches in...

A solenoid is a 3-dimensional coil. In physics, the term solenoid refers to a loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electrical current is passed through it. Solenoids are important because they can...
