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 flow.
The magnetic force acting on a straight conductor depends on the angle between the conductor and the magnetic field.
The magnetic force can perform work on the conductor, resulting in energy transfer.
The direction of the magnetic force is determined solely by the magnitude of the current.
Correct Answer
Detailed Explanation
The magnetic force on a conductor carrying current is given by F = I l × B, where the direction of force depends on the angle between the current direction and the magnetic field, making option B correct. The other options misrepresent the nature of magnetic forces.
