NEET Physics Magnetic Force on Current MCQ Question
Which of the following statements about the magnetic force on a current-carrying conductor is correct?
The magnetic force is always parallel to the direction of current.
The magnetic force can do work on the conductor, changing its kinetic energy.
The magnetic force acts perpendicular to both the current and the magnetic field.
The magnitude of the magnetic force depends only on the current in the conductor.
Correct Answer
Detailed Explanation
The magnetic force acting on a current-carrying conductor is always perpendicular to both the direction of the current and the magnetic field, which means it does not do work on the conductor and does not change the speed of the charge, only its direction.
