Could you treat it as two half infinite wires with Biot-Savart and add two finite segments on top of that? Or just two semi infinites from the correct distance. But then again I'm not sure how well Biot-Savart handles semi infinites.

Homework Statement A long wire with a current changes direction by 90 degrees. Calculate the magnetic field at the point at a perpendicular distance of S from the wire before it changed direction and a distance of T from the segment of the wire after it changed direction. Homework Equations I...
