1. Magnetic Flux

Φ = B·A = BA cosθ

Φ = NBA

2. Faraday’s Laws and Induced Emf

e = -dΦB/dt

e = -N dΦB/dt = -d(NΦB)/dt

I = e/R

q = IΔt = (N/R)ΔΦB

e ∝ 1/Δt, I ∝ 1/Δt

3. Lenz’s Law and Direction of Current

Direction of induced emf/current opposes the cause producing it

4. Methods of Changing Magnetic Flux

Φ = BA cosθ

e = BAω sinθ

e = -A cosθ (dB/dt)

∮E·dl = -dΦB/dt
