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?

Answer 1

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.
