Electrometer ❤ An electromagnet is a type of magnet that is created by passing an electric current through a coil of wire. Unlike permanent magnets, which retain their magnetism without external influence, electromagnets only exhibit magnetic properties when an electric current flows through them. The strength of the magnetic field produced by an electromagnet can be controlled by varying the amount of current flowing through the wire coil or by changing the number of coils in the wire.
