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....

Magnetic Field Generated by a Finite, Current-Carrying Wire
A steady current I is flowing through a straight wire of finite length. Find B1, the magnitude of the magnetic field generated by this wire at a point P located adistancex from the center of the wire. Assume that at P the angle subtended from the midpoint of the wire to each end is θ as shown in the diagram.
