| ASSERTION: We cannot think of magnetic field configuration with three poles. |
| REASON: A bar magnet does exert a torque on itself due to its own field. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: D
Solution :
It is quite clear that magnetic poles always exists in pairs. Since, one can imagine magnetic field configuration with three poles, when north poles or, south poles of two magnets are glued together. They provide a two pole field Configuration. It is also known that a bar magnet does not exert a torque on itself due to its own field.
