7 steps to solving electromagnetic induction problems

  1. Determine the magnetic flux that links the conductor or circuit.
  2. Identify the action that is producing the change in flux linkage.
  3. Calculate the ‘change in flux linkage’.
  4. Calculate the time taken for the ‘change in flux linkage’ to occur.
  5. Use Faraday’s law to calculate the magnitude of the induced e.m.f.
  6. Use Lenz’s law to predict direction of induced current that is set up. (This may not be applicable for opened circuit when an induced current is not allowed to flow.)
  7. Fleming’s right hand rule may also be used to find the direction of the induced e.m.f. or current where appropriate.
