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.

As the given figure shows; current is flowing clockwise through a circular loop and the direction of the magnetic field around the conductor can be known by using the Right hand thumb rule. As the figure shows,when it is inside the loop, the magnetic field would be towards the plane of the paper and On the other hand, when it is outside the loop, the magnetic field would be away from the paper.
