What Peak emf means in Physics A-Level, as defined for AQA.
Definition of Peak emf
Check what you remember
Read the wording for your board, then hide it and explain Peak emf in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
ε₀ = BANω, reached when the coil plane is parallel to B, where flux linkage is momentarily zero but changing fastest.
