Consider a circular loop of wire lying in the plane of the table. Let the current pass through the loop clockwise. Apply the right-hand rule to find out the direction of the magnetic field inside and outside the loop?

A circular loop of wire lying in the plane of the table is shown in the figure. A battery is passing a current through the loop of the wire in the clockwise direction.
Now, when we apply the Right-hand thumb rule to the left side of the circular loop, we find the direction around the anti-clockwise direction.
