Introduction: Homopolar Motor

This simple motor is very fun to make. You can use it as entertainment, or just as something to build for fun.

Step 1: Materials

To make this motor, you will need a copper wire that is at least 8 inches long, two magnets (they do not need to be ring magnets, even though that's what we used), a battery that is at least 1.5 volts and isn't dead, and pliers to make bending the wire easier.

Step 2: Bending the Wire

Once you have all of the materials, take the pliers and the wire, and then bend the wire. Try to make the wire shaped like a curved heart.(It doesn't have to be perfect!!!!!!) You may have to adjust the wire to fit around the battery.

Step 3: The Battery

Add the two magnets to the bottom of the battery. They should be pretty firmly on there.

Step 4: Putting It All Together

Place the wire so that the pointy part where the wire dips down is touching the center of the top of the wire. Make the bottom parts touch the sides of the magnets. Remember, you might have to adjust the wire a bit. Also, make sure the wire isn't too tight, or it won't spin!
