Question

A square loop in a magnetic field B

1) (i) State Faraday’s law of electromagnetic induction for the induced e.m.f. in a circuit due to changing magnetic flux.

(ii) Assume the axis of the loop is along the x-axis and the loop rotates in a clockwise direction with angular speed

Answer 1

(i)According to Faraday's law of electromagnetic induction the magnitude of induced EMF is equal to the rate of change of magnetic flux linked with the closed circuit or coil. 

$E = -N d\phi_B/dt$

(ii) please provide the complete question.
