Faraday's Law (h2, Scene Summary)

One CoilTwo Coils

"Faraday's Law‬ is an interactive sim. It changes as you play with it.

At the centre of the play area is a coil connected to a light bulb circuit. There is a also moveable bar magnet.

Grab the magnet to play.

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."

Bar Magnet (h3)

One CoilTwo CoilsRelative Coil Proximity Values

The bar magnet is (relative coil proximity)* 4 loop coil.

North pole on left. South pole on right.

The bar magnet is (relative coil proximity)* 4 loop coil.

The bar magnet (relative coil proximity)* 2 loop coil.

North pole on left. South pole on right.

  • (just) above
  • (just) below
  • (just) left of
  • (just) right of
  • touching
  • inside

*Two proximity values can be used to describe location - above/below, and left/right. See examples below.

Examples:

Special case: Magnet above / below and far from both coils

Special case: Magnet above / below and closer to one coil than the other
