Lesson Plan: Inductance Physics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the self-inductance of a conducting loop and the mutual inductance of a pair of conducting coils.


Students will be able to

  • understand that a current-carrying conducting coil induces a current in another coil due to the magnetic field produced by the first coil,
  • relate an induced emf to a rate of change of magnetic flux and to mutual inductance for two coils with equal number of turns, using the formulae 𝐸=𝑁ΔΦΔ𝑡 and 𝑁ΔΦ=𝑀Δ𝐼,
  • understand that the magnetic field produced by a current-carrying loop induces a change in the current in the loop,
  • relate an induced rate of current change in a loop to its self-inductance and to the emf across it and the magnetic flux produced by the current, using the formulae 𝐸=𝐿Δ𝐼Δ𝑡 and 𝐿=𝑁ΔΦΔ𝐼.


Students should already be familiar with

  • qualitative description of magnetic fields produced by current loops and by solenoids,
  • qualitative description of electromagnetic induction.


Students will not cover

  • transformation formulae.
