Electromagnetic Field Theory A rectangular loop in the x – z plane bounded by the lines x = 0, x = a, z = 0 and z = b is in a time varying magnetic field is given by B = B0 cosωt + ay. Where B0 is constant, ω is angular frequency and ay unit vector in the y direction. Now the emf induced in the loop is given by Bo ω sinω t. ab Bo cosω t. Zero. abω Bo sinω t. Bo ω sinω t. ab Bo cosω t. Zero. abω Bo sinω t. ANSWER DOWNLOAD EXAMIANS APP
