Faraday's Law (h2, Scene Summary)

ExampleDescription Template*

Faraday's Law‬ is an interactive sim. It changes as you play with the movable bar magnet.

At the centre of the play area are a 2 loop and a 4 loop coil connected to a light bulb circuit. A voltmeter is also attached to the circuit.

The two coils are sideways, each with openings on the left and right.

Magnetic field is weak at the 2 loop coil, moderate magnetic field at the 4 loop coil.

Grab the magnet to play.

There are additional controls that change what is connected to the circuit, flip the bar magnet, and reset the sim. If needed, check out keyboard shortcuts under Sim Resources.
