Type: Assertion Reason-assertion-Easy-Class 12
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.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
