Suppose we want to verify the analogy between electrostatic and magnetostatic by an explicit experiment. Consider the motion of (i) electric dipole p in an electrostatic field E and (ii) magnetic dipole M in a magnetic field B. Down a set of conditions on E, B, p, M so that the two motions are verified to be identical.

Three identical bar magnets are riveted together at centre in the same plane as shown in figure. this system is placed at rest in a slowly varying magnetic field. It is found that the system of magnets does not show any motion. The north – south poles of one magnet is shown in the figure. determine the poles of the remaining two.
