alleryStart learning →Faraday's law of electromagnetic induction:
AEMF induced = -dΦ/dt (rate of change of flux linkage)
BΦ = constant
CΦ = V
DNo EMF
Answer & Solution
Correct answer: A. EMF induced = -dΦ/dt (rate of change of flux linkage)
**Faraday's law:** ε = -dΦ/dt (for single turn) or -N dΦ/dt (for N turns).
Negative sign by Lenz's law (induced current opposes flux change).
Basis of transformers, generators, induction motors.
