NEET Physics Magnetic Force on Current MCQ Question
Which of the following statements about the magnetic force on a current-carrying conductor are correct?
The magnetic force on the conductor does work if it is perpendicular to the velocity of the charged particles.
The magnetic force is always directed perpendicular to both the magnetic field and the current direction.
A current-carrying conductor in a uniform magnetic field will experience a net force only if the field is not parallel to the conductor.
The magnetic force on a conductor can change the speed of the charged particles within it.
Correct Answer
Detailed Explanation
The magnetic force on a current-carrying conductor is always directed perpendicular to both the magnetic field and the current direction, which means it does not do work on the moving charges, and thus does not change their speed, only their direction.
