A magnetic field around a conductor is a good indication that current is flowing.

Question

Quizplus · Accepted Answer

A magnetic field is created around a conductor when there is a flow of current. This is known as the right-hand thumb rule, which states that the direction of the magnetic field is perpendicular to the direction of current flow and follows the curl of your right-hand fingers around the conductor. Therefore, the presence of a magnetic field around a conductor indicates the flow of current.
