This chapter focuses on the use of some very simple materials to produce an electric motor with which to demonstrate the principles of magnetism. A variation of the simple motor replaces the usual ceramic magnet with a coil of wire to form an electromagnet. Both pieces are fairly simple to build and can be entertaining as well as instructional. The simple motor is an engaging activity for students in grades four and higher.
