Question

When is the force experienced by a current-carrying straight conductor placed in a uniform magnetic field.

1. Maximum
2. Minimum

Answer 1

1. The force experienced by a current-carrying straight conductor placed in a uniform magnetic field is maximum when the conductor-carrying current is perpendicular to the direction of a uniform magnetic field.
2. The force experienced by a current-carrying straight conductor placed in a uniform magnetic field is minimum when the conductor-carrying current is parallel or anti-parallel to the direction of a uniform magnetic field.
