Question 14.8: A rectangular wire loop of sides 8cm and 2cm with a small cut is moving out of region of uniform magnetic field of magnitude 0.3T directed normal to the loop. What is the emd developed across the cut if the velocity of the loop is 1cm/s in a direction normal to the (a) longed side, (b) shorter side of the loop? For how long does the induced voltage last in each case?
