Figure shows a square loop of resistance 1 of side 1 m being moved towards right at a constant speed of 1 m/s. The front edge enters the 3 m wide magnetic field (B = 1 T) at t = 0. Draw the graph of current induced in the loop as time passes. (Take anticlockwise direction of current as positive)

Time taken for the coil to completely enter the magnetic field =speedlength=11=1sec Now side BC is1minside magnetic field Time taken for side BC to reach other end=12=2sec While entering E=(dt/dϕ)=d/dt(B.A)=d/dt(Bxl)=B.ldx/dt=BlV=1×1×1=1i=RE=11=1A
