NEET Physics Bar Magnet Assertion Reason Question
Assertion (A): A bar magnet in a uniform magnetic field experiences zero net force.
Reason (R): The torque on a bar magnet in a uniform magnetic field is given by the vector product of its magnetic moment and the magnetic field.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that when a bar magnet is placed in a uniform magnetic field, the force on it is zero, and the torque is m × B, confirming both statements and their relationship.
