This is a standards-based lab for grades 9-12 that explores how energy is converted in a simple electromagnet, using materials that are readily available at hardware stores. The electromagnet is constructed by wrapping a 4-inch nail with copper magnet wire. The experiment was designed to give students a basis for understanding how an AC source produces currents that flow in one direction and then the other. The lesson includes illustrated instructions for teachers and ideas for assessment.

This web page is part of the PBS Online resource collection on the life of Nikola Tesla. SEE RELATED MATERIALS for a link to a closely related lesson on converting mechanical energy into electrical energy.
