Grade 10Electrostatics

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​
