Question:
Three identical bar magnets are riveted together at the centre in the same plane as shown in the 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.
Solution:
The system will have a net torque and the net force equal to zero as the system is in equilibrium.
