Answer:
Correct Answer: D
Solution:
It is quite clear that magnetic poles always exist in pairs. Since, one can imagine a magnetic field configuration with three poles. When north poles or south poles of two magnets are glued together. They provide a three pole field configuration. It is also known that a bar magnet does not exert a torque on itself due to its own field.
