Flux, Faraday’s and Lenz’s laws, and induced e.m.f. for the HL induction topic.

Mastery checklist

Know what success looks like.

  1. 01

    Identify the source of the field and distinguish field direction from force direction.

  2. 02

    Use vector superposition or flux reasoning without dropping signs or geometry.

  3. 03

    Connect the field model to force, energy, or induced e.m.f. in the mapped situation.

Exam lens

Build, apply, check.

D.4 Induction is identified as HL only in this curriculum map. Build the concept first, then practise selecting a model, showing working, and checking the final result.
