Q44 · Physics

A very long conducting wire is bent in a semi-circular shape from AA to BB as shown in figure. The magnetic field at point PP for steady current configuration is given by :

The figure, described in words

Two long parallel straight wires (current i rightward on top ending at A, leftward on bottom from B) joined by a semicircle of radius R from A to B, bulging left (toward the wires); P is the centre of the semicircle.
