An electromagnet is a magnet that is created using an electric current -- created by electricity. Since electricity can be turned on and off, so can an electromagnet. It can even be weakened or strengthened by decreasing or increasing the current. Also when charges, like electrons or protons, are stationary, they produce electric forces. But when they're moving, they produce magnetic forces.
