Consider a circular loop of wire lying in the plane of the table. Let the current pass through the loop clockwise. By applying the right hand rule, how can we find out the direction of magnetic field inside and outside the loop?

Here, we can applying the right hand thumb rule to determine the direction of the magnetic field.

Now, refer to the figure below...

Here, the current is flowing in a clockwise direction in a circular loop. The direction of the magnetic field inside the loop are going into the table while outside the loop are coming out of the table.
