If B is the flux density, I the length of conductor and v the velocity of conductor, then induced e.m.f. is given by______________?
Correct answer: A. Blv
- A. Blv
- B. Blv2
- C. Bl2v
- D. Bl2v2
Explanation
For a conductor of effective length l moving at velocity v through flux density B, the motional emf is e = Blv when the motion is perpendicular to the field. The squared terms in the other options have no physical basis.
