 |
5K 10.20 - Induction Coil with Magnet & Galvanometer:
Demonstrates: Faraday's Law.
Description: A magnet and a wire coil are used to measure a magnetic field caused by current.
|
 |
5K 10.40 - Toroidal Solenoid:
Demonstrates: Amphere's Law.
Description: The toroid is wires wrapped around a doughnut shape.
|
 |
5K 20.10 - Eddy Currents in Pendulum:
Demonstrates: Eddy currents.
Description: Eddy current field will stop arm when solid aluminum paddle is inserted, other paddles will not stop.
|
 |
5K 20.25 - Magnet in Eddy Tubes:
Demonstrates: Induced currents.
Description: A magnet and non-magnet are dropped through a copper tube; one falls faster.
