Question

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.

Answer 1

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.
