Materials List: Induced EMF in a Coil of Wire

Each group needs:

  • 2 gilley coils*
  • rubber-coated NdFeB magnet
  • multimeter
  • 6V lantern battery or 5V DC power wupply
  • 1000-ohm resistor
  • 3 wires with alligator clip leads
  • several hookup wires
  • diode
  • LED
  • 100 μF capacitor
  • breadboard
  • Induced EMF in a Coil of Wire Handout, one per student

* Gilley coil induction sets are available online from a number of venders for ~$50. Improvise an easy alternative by winding a 2-inch diameter coil of 100 turns using 20 gauge magnet wire held together with duct tape.
