5.k10.28a Induction Coil Demo

Demonstrate that an induced current is created in closed loops by dropping a magnet through two coils of wire. Drop the magnet through the loops without closing them to show that the magnet falls right through. 

*WARNING* The magnet is VERY strong and must not be placed near ferromagnetic materials. Store magnet in plastic container when not in use. 

Closed loops with wires

Closing the loops with a wire slows the magnet as it goes through each coil (simmilar to the eddy current tube). 

Closed loops with LEDs

Closing the loops with LEDs will show that a current is indeed induced as the LEDs will flash as the magnet passes through.
