1 | Break a Magnet | Magnets |
A broken magnet still exhibits north and south poles. |
|
2 | Paramagnetism and Diamagnetism | Paramagnetism and Diamagnetism |
Paramagnetic and diamagnetic crystals are inserted between the poles of a large magnet or electromagnet. |
|
3 | Curie Point | Temperature and Magnetism |
Iron under magnetic attraction is heated until it falls away. Upon cooling it is again attracted. |
|
4 | Meissner Effect | Temperature and Magnetism | Place a magnet on warm superconducting disk to show how nothing happens, then remove. Add LN2 to the Styrofoam container holding the super conducting disk. When the boiling stops, the disk is cold. Use the plastic tweezers to place one of the magnets on the disk. The magnet will float above the disk. | |
5 | Oersted's Effect | Magnetic Fields |
Turn the compass needle so it is approximately parallel to the wire. Close the switch to send the current through the wire for about 5-10 sec. The compass will align itself with the magnetic field. |
|
6 | Magnet and Iron Filings | Magnetic Fields |
Sprinkle iron filings on the Plexiglas plate. Tap the Plexiglas to encourage alignment. |
|
7 | Magnetic Field Around Wire | Fields and Currents |
Sprinkle iron filings on the Plexiglas. Hold down the switch briefly connecting the bottom while tapping the Plexiglas to encourage alignment. |
|
8 | Solenoid and Iron Filings | Fields and Currents |
Sprinkle iron filings on the Plexiglas. Hold down the tap switch briefly connecting the bottom while tapping the Plexiglas to encourage alignment. |
|
9 | EM Vectors | Transmission Lines and Antennas | A dynamic model for demonstrating electric and magnetic vectors in an electromagnetic field. | |
10 | Projected Spectrum w/Prism | Electromagnetic Spectrum |
White light is projected through a high dispersion prism and onto a screen. |
