| Demonstrates: Lenz's Law, Faraday's Law, Magnetic Levitation |
| Description: A ring is placed atop the solenoid which has an iron core. When AC power is supplied to the solenoid, the changing magnetic flux induces a current in the metal ring. The induced magnetic field of the ring is opposite the field of the solenoid and the ring is repelled off into the air. A split ring does not allow current to flow, and does not fly off.
|
| Instructions: Place ring over iron core, press switch, adjust iron core cool ring in LN2 for effect/difference.
|
| Items Used: Solenoid with variable iron core, various rings of aluminium, iron, copper, LN2 Notes: The effect can be increased dramatically if the ring is cooled in liquid nitrogen first. Math Description: None.
Size: 19 Condition: Good. Hazard: Avoid looking directly over rings when pressing switch,LN2
