Show the magnetic field lines for a current-carrying loop. Write the rule for finding the direction of a magnetic field due to a circular current loop.
(N/A) The magnetic field lines due to a circular current-carrying loop form closed loops, as shown in the figure.
The direction of the magnetic field is determined by the Right-Hand Thumb Rule:
"Curl the fingers of your right hand around the circular wire such that the fingers point in the direction of the current. The extended right-hand thumb then points in the direction of the magnetic field at the center of the loop."
