This is a pre-assembled DC Motor designed for students to learn about electromagnetic forces. The open structure resembles the diagram found in many textbooks. The polarity of the magnets can be reversed to change the direction of the rotation. The motor can also be used with a rheostat to observe the change of speed with the change of current.
This Floating Magnet Set contains 6 brightly colored magnetic rings, and the plastic stand, in a cardboard storage box. We have designed a special stand to replace the pencil, for hands-free demonstration. Magnets are in plastic cases, to reduce breakage.
These Alnico U Shaped Magnets are painted red and supplied with a keeper.
