- Electromagnet - Wikipedia
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current Electromagnets usually consist of wire (likely copper) wound into a coil A current through the wire creates a magnetic field which is concentrated along the center of the coil The magnetic field disappears when the current is turned off
- Electromagnet | Uses, Properties Applications | Britannica
electromagnet, device consisting of a core of magnetic material surrounded by a coil through which an electric current is passed to magnetize the core An electromagnet is used wherever controllable magnets are required, as in contrivances in which the magnetic flux is to be varied, reversed, or switched on and off
