Q. 25.0( 2 Votes )

See fig. Q-2, magnetic lines are shown. What is the direction of the current flowing through the wire?


Answer :

According to the Right-Hand Thumb Rule. If we curl our fingers in the direction of the magnetic field lines than the thumb gives the direction of the flow of current.

In the above figure, the direction of magnetic field is anticlockwise Thus by curling our fingers in the anticlockwise direction the thumb points upwards. Therefore, the direction of the current is upwards. The figure below illustrates the same.
