Physics-Magnetic Force on Current
NEET Physics Magnetic Force on Current MCQ Question
Type: MCQ-numerical-Hard-Class 12
A straight conductor of length 0.5 m carries a current of 12 A and is oriented at an angle of 45° with respect to a uniform magnetic field of 0.2 T. What is the magnitude of the magnetic force experienced by the conductor?
A
0.85 N
B
1.7 N
C
0.6 N
D
1.3 N
Correct Answer
Option C
Detailed Explanation
The magnetic force on a current-carrying conductor is given by F = I * l * B * sin(θ). Substituting the values: F = 12 * 0.5 * 0.2 * sin(45°) = 0.6 N.
