Induced currents

Eb-1 Arago's Disc

Published: Tuesday 14 March 2006

To demonstrate the presence of induction currents when there is relative motion between a conductor and a magnetic field.

Eb-2 Faraday's Law of Induction

Published: Tuesday 14 March 2006

To demonstrate the generation of an EMF in a coil threaded by a changing magnetic field.

Eb-3 Faraday's Wheel

Published: Tuesday 14 March 2006
