NEET Physics Bar Magnet Assertion Reason Question
Assertion (A): A short bar magnet experiences a torque when placed with its axis at an angle to an external magnetic field.
Reason (R): A bar magnet aligns itself along the direction of the magnetic field to minimize its potential energy.
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.
Correct Answer
Detailed Explanation
A bar magnet placed at an angle to a magnetic field experiences a torque because it tends to align itself along the field direction to minimize potential energy.
