Question

A current carrying wire kept in a uniform magnetic field, will experience a maximum force when it is ______.

पर्याय

• perpendicular to the magnetic field

• parallel to the magnetic field

• at an angle of 45° to the magnetic field

• at an angle of 60° to the magnetic field

Answer 1

A current carrying wire kept in a uniform magnetic field, will experience a maximum force when it is perpendicular to the magnetic field.

Explanation:

F = Bilsin θ

θ is the angle between the current's direction and the magnetic field's direction.

So, when θ = 90°, the force is maximum.
