An electromagnetic door lock uses an electromagnet to pull a magnetic bolt to unlock a door. An electric bell often contains an electromagnet that attracts and moves the striker, making it hit the bell. As an electromagnet moves the striker in an electric bell, it breaks its own circuit to let the striker spring back. A motor contains a spinning coil of wire that is an electromagnet. When there is a current in the spinning coil of wire in a motor, other magnets around it will push it round.
