NEET Physics Magnetic Force on Current MCQ Question
What is the orientation of stable equilibrium for a current-carrying loop in an external magnetic field?
The area vector A of the loop is parallel to the external magnetic field.
The area vector A of the loop is perpendicular to the external magnetic field.
The area vector A of the loop is at an angle of 45 degrees to the external magnetic field.
The area vector A of the loop is randomly oriented in the magnetic field.
Correct Answer
Detailed Explanation
The stable equilibrium occurs when the area vector A of the loop is in the direction of the external magnetic field, maximizing the flux of the total field.
