A square loop of side 20 cm is initially kept 30 cm away from a region of uniform magnetic field of 0.1 T as shown in the figure. It is then moved towards the right with a velocity of 10 cm s?1 till it goes out of the field. Plot a graph showing the variation of
(i) magnetic flux (?) through the loop with time (t).
(ii) induced emf (?) in the loop with time t.
(iii) induc ed current in the loop if it has resistance of 0.1 ?.
