Noun. 1. electromagnet-a temporary magnet made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet. armature-coil in which voltage is induced by motion through a magnetic field. electric bell-a bell activated by the magnetic effect of an electric current.
In an electromagnet a coil, of a large number of circular turns of insulated wire, wrapped on a cylindrical core, behaves like a magnet when an electric current flows through it. When the current is switched off, the coil loses its magnetism immediately. We call such a device as an electromagnet.
