NEET Physics Magnetic Force on Current MCQ Question
Type: MCQ-fact-Medium-Class 12
What is the formula for the magnetic force experienced by a straight conductor of length l carrying a steady current I in a uniform magnetic field B?
A
F = I l × B
B
F = B I l
C
F = I B l
D
F = l I B
Correct Answer
Option A
Detailed Explanation
The force experienced by a straight conductor carrying a steady current in a uniform magnetic field is given by the formula F = I l × B, where l is the length of the conductor and the direction of l is given by the direction of the current.
