NEET Physics Magnetic Force on Current MCQ Question
Which of the following statements about the magnetic force on a current-carrying wire is correct?
The direction of the magnetic force is perpendicular to both the magnetic field and the current direction.
The magnetic force increases as the angle between the current and magnetic field approaches 90 degrees.
The magnitude of the magnetic force is independent of the current flowing through the wire.
The magnetic force acts in the same direction as the current in the wire.
Correct Answer
Detailed Explanation
The magnetic force on a current-carrying wire is given by the formula F = I × B × sin(θ), where θ is the angle between the current and magnetic field. Hence, the direction of the force is indeed perpendicular to both the magnetic field and the direction of the current.
