Kinetic (mechanical) energy to electrical energy
Electromagnetic induction
ΦB=ABsinθ\Phi_B = AB \sin \thetaΦB=ABsinθ
ε=−dΦBdt\varepsilon = -\frac{d\Phi_B}{dt}ε=−dtdΦB
Zero (flux is momentarily constant)
Converts AC in coil to DC in external circuit
Provide electrical connection between coil and external circuit
Produces smoother, more constant DC output
Stronger fields, self-excitation, field control
When flux is zero and changing most rapidly
