What is an electromagnet? An electromagnet is a magnet that runs on electricity. An electromagnet works because an electric current produces a magnetic field. If a wire carrying an electric current is formed into a series of loops, the magnetic field can be concentrated within the loops.
An electromagnet is a coil of wire that s magnetic only when an electric current flows through it. To make an electromagnet even stronger, its wire is usually wound around iron or another magnetic material. The field from the wire magnetizes the core (see text pg 281-5).
