The force on a current-carrying conductor in a magnetic field is maximum when the conductor is

A. Parallel to field

B. At 60°

C. At 45°

D. Perpendicular to field

Answer: Option D

Solution (By JKExamLibrary)

F = BIL sinθ. Maximum when θ = 90° (sin90°=1), so perpendicular. Parallel (θ=0°) force zero. This is the motor effect, used in electric motor.
