The magnitude of the induced e.m.f. in a conductor depends on the______________?
Correct answer: D. rate of change of flux-linkages
- A. flux density of the magnetic field
- B. amount of flux cut
- C. amount of flux linkages
- D. rate of change of flux-linkages
Explanation
Faraday’s law gives induced emf as e = −dλ/dt, where λ is flux linkage. Thus the magnitude depends on the rate of change of flux linkages, not merely their amount.
