Lesson Plan: Inductance Physics • Third Year of Secondary School
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.
Objectives
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 and ,
- 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 and .
Prerequisites
Students should already be familiar with
- qualitative description of magnetic fields produced by current loops and by solenoids,
- qualitative description of electromagnetic induction.
Exclusions
Students will not cover
- transformation formulae.
