Electromagnetic Induction
Discussion
Introduction
What's the right way to divide these sections up?
Motional emf (electromotive force)
ℰ = Bℓv
Electromagnetic induction and emf
| ℰ = − | ∆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.
