emf induced in a circuit according to Faradays law depends on the_____________?
Correct answer: B. rate of change of magnetic flux
- A. maximum magnetic flux
- B. rate of change of magnetic flux
- C. change in magnetic flux
- D. initial magnetic flux
Explanation
Faraday’s law states that induced emf is proportional to the rate of change of magnetic flux, expressed as e = -N(dΦ/dt). A steady flux, even if large, produces no induced emf.
