Question

A circular loop with 30 turns and area of 0.25 m2 rotates at 100 rad/s. The axis of rotation of the loop is perpendicular to the direction of the magnetic field of 0.04 Tesla. What is the maximum emf induced in the loop?


15 V

30 V

45 V

60 V


I got 15 V but that doesn't seem quite right

Answer 1

ℰ(max) =NBAω =30•0.04•0.25•100 = 30
