This Eddy Current Demonstrator consists of a 12" long copper tube and two apparently identical metal slugs with rubber end caps. One slug is plain steel and falls through the copper tube quickly. The other slug is a strong neodymium magnet that falls very slowly through the tube due to the breaking effect of eddy currents.

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.
