    1. Magnetic Field Generated by a Current in a Wire Under steady-state conditions, a magnetic field B has curlB in a region where there is no current. We study the steady-state magnetic field B due to a constant current in an infinitely long straight thin wire. The magnitude of the magnetic field at a point depends only on the distance from the wire and its direction is tangent to the circle around the wire and determined by the right-hand rule....
