NEET Physics Bar Magnet MCQ Question
Which of the following statements about a bar magnet is correct?
A bar magnet experiences zero net force when placed in a uniform magnetic field.
The magnetic moment of a bar magnet is always aligned with the magnetic field.
A bar magnet can be broken into two separate magnetic poles.
The torque experienced by a bar magnet in a magnetic field is independent of its magnetic moment.
Correct Answer
Detailed Explanation
When a bar magnet is placed in a uniform magnetic field, it experiences zero net force, as the forces on the opposite poles cancel each other out. This is consistent with the statement that the torque is given by m × B, but the force is indeed zero.
