A current carrying coductor creates a magnetic field. A solenoid coil carrying current behaves like a bar magnet. This can be demonstrated by placing a compass needle or a small magnet near the coil. The coil that comes with the kit consists of 3000 turns of SWG44 wire. It has an inductance of around 120 mH and around 500 Ohm resistance.
The experiment may be repeated using WG, set to low a frequency.
