Electric current produces a magnetic field. The magnetic field can be
visualized as a pattern of circular field lines surrounding the wire that persists
as long as there is current.
Magnetism can also produce electric currents. When a changing magnetic

When analyzing electrical circuits, the actual direction of current through a
specific circuit element is usually unknown. Consequently, each circuit
element is assigned a current variable with an arbitrarily chosen reference
