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.

Solution
Right-hand rule:
If we hold the conductor inside the palm of our right hand with the thumb pointing the magnetic field's direction, the direction wherein our fingers curl indicates the direction of the current.
A circular loop of wire carrying current:
The current flows clockwise via a circular loop, as shown in the diagram. This same right-hand thumb rule may be utilized to determine the direction of the magnetic field surrounding the conductor.
The diagram is shown below:
The direction of magnetic feild will be downward. Inside the loop it will be downwars and outside the loop it will be outward in direction.
