alleryFaraday's law says the induced emf equals the time rate of change of:
ACoil resistance
BWire length
CMagnetic flux
DElectric charge
Answer & Solution
Correct answer: C. Magnetic flux
1. Every experiment showed emf only while flux was changing.
2. Faraday wrote this as a rate of change.
3. The emf equals the rate of change of magnetic flux.
