Which diagram correctly shows the magnetic field lines created by a circular current loop in which current flows in the direction shown?

Question

Quizplus · Accepted Answer

The magnetic field lines created by a circular current loop are perpendicular to the plane of the loop and run in circles around the wire. Using the right-hand rule, we can determine that the direction of the magnetic field inside the loop is into the plane of the paper and out of the plane of the paper outside the loop. Choice C correctly shows the circular pattern of magnetic field lines with the proper direction.
