NEET Physics Magnetic Force on Current MCQ Question

Type: MCQ-diagram based-Medium-Class 12

Consider a diagram showing a current-carrying wire placed within a uniform magnetic field. The wire carries a current I and makes an angle θ with the magnetic field B. Which of the following expressions correctly represents the magnitude of the magnetic force F acting on a segment of the wire of length l?

Question diagram
A

F = I l B sinθ

B

F = I l B cosθ

C

F = I l B tanθ

D

F = I l B

Correct Answer

Option A

Detailed Explanation

The magnetic force on a current-carrying wire in a magnetic field is given by F = I l B sinθ, where θ is the angle between the wire and the magnetic field, as shown in the NCERT context.
