Here's how to make an easy homemade motor:
.A disc magnet
.A sharp pointed wood or drywall screw
1-Set the screw in the center of the disk magnet.
2-Cut the alligator test lead in half, and strip the insulation from the last inch of the cut end, so the strands of wire spread out like a brush.
3-Hold the alligator clip against the flat end of the battery.
4-Bring the button end of the battery to touch the point of the screw, and lift the screw and magnet an inch off the table (the screw will stick to the battery because of the magnet).
5-Gently hold the brush end of the wire against the edge of the magnet.
And now watch the wire turn around the battery functioning as a motor!!!
