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.

The right-hand rule is a useful tool to determine the direction of the magnetic field around a current-carrying conductor or a loop. In this case, you can use the right-hand rule to find the direction of the magnetic field both inside and outside the circular loop of wire.

1. For the Outside of the Loop:

Point your thumb in the direction of the current (clockwise in this case).
Extend your fingers. The curling of your fingers gives you the direction of the magnetic field lines around the wire. The direction is then perpendicular to the plane of the loop.
So, for a clockwise current in the loop, the magnetic field outside the loop will be circulating counterclockwise if viewed from above.

2. For the Inside of the Loop:

Again, point your thumb in the direction of the current (clockwise).
Curl your fingers inside the loop. The direction of the magnetic field lines inside the loop is then along the axis of the loop, toward the center.
Therefore, for a clockwise current in the loop, the magnetic field inside the loop will be directed toward the center of the loop.

Remember, the right-hand rule is a convention, and the direction of the magnetic field can be reversed if the direction of the current is reversed.
