Possible Activities

Want to know how you can use this product in your science lessons? Take a look at the list of possible use cases and activities to get you started with the Wire Coil & Magnet.

  • Faraday's law of induced e.m.f. (induced by a magnet falling through the wire coil)
  • Induced e.m.f. when a magnet spins in a coil
  • The effect of speed of the magnet on induced e.m.f, e.g. dropping the magnet from different heights.
  • Two Wire Coils can be set at a distance apart equal to their radius in a Helmholtz arrangement to generate an area of uniform magnetic field intensity between the coils. A Magnetic Field sensor (3170) can be used to study the magnetic field along their axis.
  • Measuring e.m.f. and change in magnetic field to study how rate of change of magnetic field creates voltage and current.
