introduction

What's the right way to divide these sections up?

Motional emf (electromotive force)

ℰ = Bℓv

Electromagnetic induction and emf

 = − ∆ΦB
t
ℰ = − dΦB
dt

A more advanced form written as an bunch of integrals

E · ds = − ∂ΦB
t

A more advanced form written as a bunch of derivatives

∇ × E = − B
t

Lenz' law: Induced current flows in the direction that opposes the change that created it.
