A current-carrying conductor is placed in a magnetic field. The force on it is maximum when the current is directed:
AOpposite to the magnetic field
BParallel to the magnetic field
CPerpendicular to the magnetic field
DAt 45° to the magnetic field
Answer & Solution
Correct answer: C. Perpendicular to the magnetic field
1. The force on a current-carrying conductor depends on the directions of the current and the field.
2. The chapter states this force is maximum when the current is perpendicular to the magnetic field.
3. The option when current is parallel to the field, no useful force acts, so it is the wrong choice.
