Question

When a current-carrying conductor is placed in a magnetic field, it experiences a mechanical force. What should be the angle between the magnetic field and the length of the conductor so that the force experienced is (i) zero and (ii) maximum?

Answer 1

1. The angle should be 0° (or 180°), which means the current-carrying conductor is placed parallel to the direction of the magnetic field.
2. The angle should be 90°, which means the current-carrying conductor is placed perpendicular to the direction of the magnetic field.
