Question
The magnetic field associated with a current-carrying straight conductor is in anticlockwise direction. If the conductor was held along the east-west direction, what will be the direction of current through it? Name and state the rule applied to determine the direction of current?
Solution
It is given that the magnetic field associated with a current-carrying straight conductor is in anticlockwise direction. Further, the conductor was held along east–west direction; therefore, according to right hand thumb rule, the direction of current through it will be from east to west.
