In this activity, students will demonstrate the generator effect, which is due to electromagnetic induction when a conductor (a long metal wire) moves through a magnetic field. Materials required to this activity include: a 100-foot extension cord with ground prong, current or voltage galvanometer, two lead wires with alligator clips on at least one end, and one compass. This activity must be done in an open space large enough to swing a 100-foot cord as a jump rope, such as a gymnasium or outdoor field. This is activity three of "Exploring Magnetism." The guide includes science background information, student worksheets, glossary and related resources.
