Question
No force acts on a current-carrying conductor when it is:
- Perpendicular to the magnetic field
- Parallel to the magnetic field
- Far away from the magnetic field
- Far away from the magnetic field
Hint:
Parallel to the magnetic field
The correct answer is: Parallel to the magnetic field
The force acting on a current current conductor is given by, F = BILsinø.
If the conductor is kept parallel to the magnetic field ø = 0, F = 0. Thus, no force acts on the conductor when it is kept parallel to the magnetic field.
