Physics-Magnetic Force on Current
NEET Physics Magnetic Force on Current MCQ Question
Type: MCQ-diagram based-Easy-Class 12
In the diagram shown above, a straight conductor of length l carrying a current I is placed in a uniform magnetic field B. Which expression correctly represents the magnetic force F experienced by the conductor?
A
F = I l × B
B
F = q (v × B)
C
F = qE
D
F = μ0 I e
Correct Answer
Option A
Detailed Explanation
The magnetic force on a straight conductor carrying current I in a uniform magnetic field B is given by F = I l × B, where l is the length of the conductor.
