A, has broken off. The unshielded part of the wire is x 0.025 meters long. The shielded
parts of the wire do not contribute to the magnetic field outside the wire. Point P is above
the right-hand end of the unshielded section, a distance x/2 above the wire. The current
flows to the right (in the positive direction) as shown. The small length of wire, dl, a
distance / from the midpoint of the unshielded section of the wire, contributes a
differential magnetic field dB at point P. Ignore any edge effects.
