Location: 
Cd5
A solid plate pendulum is passed through the gap of a powerful magnet, dramatically demonstrating eddy currents. Then a slotted pendulum is used, with dramatic contrast.

Musical Coils

The keyboard plays music with its speaker off through the coil.

Demonstrates magnetic induction using two coils and a keyboard.

Induction coils with battery

No current and no deflection on the galvanometer from the second coil.

Location: 
Changing the current in one coil causes a current in the other.

Current - coupled pendula

The polarity can be reversed so that the coils swing toghether or out of phase.

Interconnected coils are hung as pendula in the gaps of two horseshoe magnets. Start one swinging and the other swings.

Eddy current tube

Clamp the camera to the table since it is close to the edge.

Powerful magnets are dropped through a copper tube. They pass very slowly due to eddy currents.

Eddy current levitation

CCTV is needed to show the levitating magnet to the class.
