Final answer:
Moving a magnet quickly in and out of a coil of wire produces an electric current.
Step-by-step explanation:
Moving a magnet quickly in and out of a coil of wire produces an electric current. This phenomenon is known as electromagnetic induction, which was discovered by Michael Faraday. When a magnet moves through a coil of wire, the magnetic field of the magnet induces an electric current in the wire.
