Assertion : We cannot think of a magnetic field configuration with three poles .
Reason : A bar magnet does exerte a torque on itself due to its own field.

A

If both assertion and reason are ture and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reson are false.

Text Solution

Verified by Experts

The correct Answer is:
D
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 mangets are glued together . They provide a three pole field configuration . It is also know that a bar magnet does not exert a torque on itself due to own its field .

Assertion: When a magnetic dipole is placed in a non-uniform magnetic field, only a torque acts on the dipole. Reason: Force would also acts on dipole if magnetic field were uniform.

Assertion: The energy of charged particle moving in uniform magnetic field does not change. Reason: Work done by magnetic field on the charge is zero.
