This site from the Exploratorium provides an activity in static electricity. Everyday materials ? a Plexiglas? sheet, a piece of wool cloth, and puffed rice ? are used to show the effect of electrical forces betwe...
This site from the Exploratorium provides a simple demonstration of the interaction between a moving magnet and its induced electromagnetic field. As the magnet is dropped down a metallic tube, it induces eddy currents...
This activity is concerned with the magnetic field generated by a current-carrying wire. Two current-carrying wires are placed near each other as forces push them apart or pull them together. Materials needed,...
This activity demonstrates the magnetic field induced by a current-carrying wire. A group of compasses are arranged around the wire indicating when a magnetic field stronger than the Earth?s field is produced. M...
