[SOLVED] Induced emf: Faraday's Law and Lenz's Law Question
The plane of a conductive loop with an area of 0.020 m^2 is perpendicular to a uniform magnetic field of 0.30 T. If the field drops to zero in 0.0045 s, what is the magnitude of the average emf induced in the loop?
Given that,
Area (a) = 0.020m2
Magnetic filed (B) = 0.30 T.
When the field drops to zero,
Time taken = 0.0045 s
I have,
Induced emf = Change in flux
Time taken
= B x a cos 90
Time taken
= 0.30 x 0.020 x 1
0.0045
= 1.33 V
Is my work/answer correct?
