The Biot-Savart law enables us to calculate the magnetic field produced by a current carrying wire of arbitrary shape. We applied the law to determine the field of a long straight wire (length ) at perpendicular distance from the wire. The formula is exact for an infinitely long wire.
The Biot – Savart Law thus gives the expected result when applied to a problem corresponding to a two-dimensional point vortex. If the vortex filament in Fig. 6.4 were only semi-infinite in length and extended from Q to infinity, then the limits of integration in Eq. 6.2 would be o1 = 0 and o2 ^ n/2, leading to:
