प्रश्न
Draw a labelled diagram showing the three magnetic field lines of a loop carrying current. Mark the direction of current and the direction of magnetic field by arrows in your diagram.

उत्तर
We can see three lines representing magnetic fields. In one, the current is represented moving upwards in an anticlockwise direction, whereas in the other, it is shown moving downwards in a clockwise manner. The loop's axis is parallel to the magnetic field line in the middle.
