What's the right way to divide these sections up?
Motional emf (electromotive force)
ℰ = Bℓv
Electromagnetic induction and emf
|ℰ = −||ΔΦB|
|ℰ = −||dΦB|
A more advanced form written as an bunch of integrals
|∮E · ds = −||∂ΦB|
A more advanced form written as a bunch of derivatives
|∇ × E = −||∂B|
Lenz' law: Induced current flows in the direction that opposes the change that created it.
