Induction, Lenz's law and back emf

What this note covers

1. Flux measures the field passing through an oriented area
2. Faraday’s law predicts magnitude from the rate of change
3. Lenz’s law opposes the change, not always the original field
4. A moving conductor links magnetic force and induced emf
5. Eddy currents and self-induction have different geometries
6. Separate peak, average and circuit-response evidence
