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 set is an easy yet effective way to teach how AC and DC electricity is produced. Banana plugs can be inserted into the different connectors to change from AC to DC electricity. The unit has a clear base for easy demonstration of connections. Includes an activity guide. Dimensions: 10"x7"x9". Shipping weight 2.5 lb. AC/DC Generator Set.
