Question
In the straight wire A, current is flowing in the vertically downwards direction whereas in wire B the current is flowing in the vertically upward direction. What is the direction of magnetic field:
  1. In wire A?
  2. In wire B?
Name the rule which you have used to get the answer.
✓

Answer

  1. Clockwise.
  1. Anticlockwise.

We have used Maxwell's hand thumb rule here.
  1. In the straight wire A, current is flowing in vertically downwards direction; therefore, the direction of magnetic field around it will be clockwise.
  2. In the straight wire B, current is flowing in vertically upwards direction; therefore, the direction of magnetic field around it will be anticlockwise.
