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. ...

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 site from the Exploratorium provides a demonstration of how heat can destroy magnetism. The site contains a materials list, assembly instructions, and basic procedures for the activity. Also presented is an...

This activity from the Exploratorium contains an introduction to diamagnetic materials like water that are repelled by both poles of a magnet. A rare-earth magnet is used to repel grapes, whose main component is water,...

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...
