Procedure

Apparatus

Circular coil, ferromagnetic material, bar magnet, speaker, amplifier, connecting wire, etc..

Variable Region

Slider

• Using this slider, the number of turns of the coil can be varying.

  Measurement Region

• The show rod check box will enable and disable the rod inside the coil.
• The show Graph check box enables the amplified output graph.

Performing the simulation:

The user has the privilege to move the magnet round the stage according to the magnetic movement the rod gets magnetize and the sound produced can be heard.

• Move the magnet around the stage. Change of magnetic flux produce fluctuating current. That can be heard as noise from the speaker.
• Repeat the experiment with different situations like increase the number of coil, remove the rod,etc. And observe the result
