Magnetic Field Due to Current Carrying Circular Loop

a Square loop...

Question

a Square loop of side 5 cm being moved towards right at a constant speed of 1 cm/s. The front edge enters the 20 cm wide magnetic field at t =0. Find the emf induced in the loop at (a)t=2 s, (b) t =10 s, (c)t =22 and (d)t =30 s.

Since front edge is entering in the magnetic field therefore angle between magnetic field and the area vector of the loop is 90 degree therefore cos 90 = 0hence flux through the loop is zero therefore no induced emf will be there.
