A simple electric motor for the classroom

You are a teacher and want to teach your students about magnetism
Then why not build a simple unipolar motor with a neodymium disc magnet from our magnet shop.

You will need:

Disc magnet Ø 15.0 x 7.0 mm neodymium N45 nickel-plated
Wood screw approx. 25 mm long (the screw must have a tip)
1.5 V AA battery
A piece of flexible copper wire



Place the screw on the disc magnet



Now all you need to do is connect the copper wire to one pole of the magnet and hold the other end of the stripped wire to the side of the magnet.
You will be amazed at how fast the magnet motor rotates.
