NEET Physics Magnetic Force on Current MCQ Question
Refer to the diagram showing a rectangular loop in a uniform magnetic field. If the loop is rotated by 90 degrees about the AD axis, what will be the effect on the net force experienced by the loop?
The net force on the loop will become non-zero.
The net force on the loop will remain zero.
The direction of the net force will reverse.
The magnitude of the net force will double.
Correct Answer
Detailed Explanation
According to the NCERT context, when the loop is in the plane of the magnetic field, the net force is zero. Rotating the loop about the AD axis does not change the overall net force, which remains zero.
