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. Share with your friends Share 5 Neha Gupta answered this 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. -71 View Full Answer
