An electromagnet is a temporary magnet that is magnetized by the magnetic field produced by an electric current in a wire. Electromagnets have magnetic properties only while the current is flowing.
In the simplest form, an electromagnet is a wire that is coiled into one or more coils. This is called a solenoid. Inside this coil is a metal core -- usually an iron alloy. When electricity flows through the wire, a magnetic field is generated. While current flows, the core acts like a magnet. When the current is stopped, the core is demagnetized.
