Simulation of Ferromagnetism by a Compass Array
Paramagnetism and Diamagnetism, using Pasco Variable Gap Magnet, Pasco Magnetic Force Accessory Kit, and optionally the goosneck camera.
Induction, using large coil, Cenco meter, and the Pasco Variable Gap Magnet.
Lenz's law: using large coil, banana patch cord, and Cenco meter. Observe that coil doesn't heat up.
Force between coil and aluminum plate (partial levitation). Requires large coil, adapter from banana to line cord, and a thick plate of Al about 2-3 feet square.
True magnetic levitation with superconducting disk. Kit plus dewar of LN.
Surfaces for integration of flux through a two-turn coil. Set of examples in my office.
Standing waves.
