NEET Physics Magnetic Force on Current Assertion Reason Question
Assertion (A): A current-carrying loop in a magnetic field tends to rotate to align its magnetic moment with the magnetic field.
Reason (R): The torque on a current loop is given by the vector product of the magnetic moment of the loop 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 explains that the torque on a current loop is expressed by the vector product of the magnetic moment and the magnetic field, which causes the loop to rotate to align its magnetic moment with the field.
