Introduction: Magnetic Field

This very simple electric motor is called a homopolar motor because the magnetic field does not change direction or strength. With only three parts, it is probably the simplest motor you can possibly make.

    Like FireCrazyAlchemist said, you could use a wire hanger, just scrape off the coating and make sure you have continuity

    Hi, it's really nice! But can you give us any tips on how to bend the wire like the shapes you have made, without getting very frustated?

    You can use needle nose pliers. Sometimes called, Jewelry pliers. They can make small, sharp curls and designs.

    I found that if you put small dent in top of battery, it keeps the wire in place so doesn't fall off. Use a small nail or something with a with a point. Don't hit to hard or it will punch a hole in battery.
