Faraday's law of electromagnetic induction states EMF induced equals:
ACurrent
BRate of change of magnetic flux
CMagnetic flux
DCharge
Answer & Solution
Correct answer: B. Rate of change of magnetic flux
EMF = -dΦ/dt. The induced EMF in a closed loop equals the negative time-rate of change of magnetic flux through the loop. Negative sign captures Lenz's law (direction).
