The pattern of magnetic field lines around a current carrying circular loop is shown in the image attached.
A unique pattern can be seen in the magnetic field lines surrounding a circular loop that is carrying current. A magnetic field is produced by the loop's current flow. The right-hand rule can be used to define how the magnetic field lines are oriented.
A current-carrying circular loop's magnetic field lines are concentric circles centered on the loop's axis. Imagine holding the loop with your right hand and lining up your thumb with the direction of the current. Your fingers will wrap around the loop in the direction of the circulating magnetic field lines since that is how the magnetic field lines are oriented.
