The students should understand that a time-changing magnetic flux induces an emf ε as given by Faraday’s law of induction ε = − N9(ΔΦ/Δt)

Here are experiments our science specialists have selected to support this IB* topic.

Faraday’s Law: Moving Magnet

Experiment #11 from Advanced Physics with Vernier — Beyond Mechanics

In this experiment, you will

  • Fashion a simple coil to collect data.
  • Collect potential vs. time data for a magnet moving through a coil.
  • Account for features of the observed graph of potential vs. time.
  • Relate the induced emf to changes in the magnetic flux passing through a coil.
