MCQ
A current-carrying conductor is held in exactly vertical direction. In order to produce a clockwise magnetic field around the conductor, the current should passed in the conductor:
  • A
    From top towards bottom.
  • B
    From left towards right.
  • C
    From bottom towards top.
  • D
    From right towards left.
✓

Answer

  1. From top towards bottom.

Explanation:

It is given that the current-carrying conductor is held in exactly vertical direction. In order to produce a clockwise magnetic field around the conductor, the current should be passed in the conductor from top towards bottom. It is concluded by applying right-hand thumb rule.
