|Three identical bar magnets are rivetted together at centre in same plane as shown in figure. This system is placed at rest in a slowly varying magnetic field. It shows that system of magnets does not show any motion. The N-S poles of one magnet is shown in the figure. Determine the poles of remaining two.|
The system of magnets will be in stable equilibrium. If the net force on the system is zero and net torque on it is also zero. It will be possible, if the poles of the remaining two magnets is as shown in the figure.
