Question

A single conducting loop of wire has an area of7.3×102 m2 and a resistanceof 100 . Perpendicular to the plane of the loop is amagnetic field of strength 0.41 T. At what rate (in T/s) must this field change if the inducedcurrent in the loop is to be 0.35 A? A single conducting loop of wire has an area of7.3×102 m2 and a resistanceof 100 . Perpendicular to the plane of the loop is amagnetic field of strength 0.41 T. At what rate (in T/s) must this field change if the inducedcurrent in the loop is to be 0.35 A?

Explanation / Answer

   Flux = B.A            d/dt= A.dB/dt d/dt =emf induced = I.R          A.dB/dt = I.R              dB/dt =I.R/A = 0.35x100/7.53x10-2                        =479.5 T/s
