Safely apply a large current to 2 pivoting brass tubes to demontrate the effect of magnetic forces between 2 current-carrying parallel conductors. The fuse-protected unit offers a simple, direct method for accomplishing this usually difficult and often unsatisfying demonstration. Includes instructions.

A basic property of electromagnetism is the mechanical force that exists between 2 neighboring, current-carrying conductors. This was first observed by Oersted in June 1820 and was rapidly investigated by him, as well as by Ampère, Biot, and Savart, so that the theory was developed by the end of the same year.
