This simple direct current (DC) motor has been created by pairing a permanent magnet and an electromagnet. The permanent magnet is called a stator because it doesn’t move. The electromagnet is a spinning coil of wire and is often called the rotor. A battery is connected to the circuit, and a magnetic field is created when current flows through the wire. That magnetic field interacts with the field of the permanent magnet, and the coil turns until the two fields are aligned.

Metals conduct electricity because their atoms have free electrons that can move between them. As those free electrons move through the metal conductor, some of them crash into things along the way like protons, neutrons, and even other electrons. Those collisions give “resistance” to the movement of the free electrons and generate heat. The resistance is increased further if the metal is exposed to an outside heating source, which causes all particles in the material to move more.
