Summary

Reconstruction of Joseph Henry's original oscillating electromagnet motor, which he had first constructed at Princeton University in the 1830s. The motor was a simple device whose moving part was a straight electromagnet rocking on a horizontal axis. Henry, who would later become the first Secretary of the Smithsonian Institution, believed his machine was important as the first demonstration of continuous motion produced by magnetic attraction and repulsion.
