WebThe Biot Savart Law is an equation that shows how magnetic fields are made when there is a steady flow of electricity. Magnetic field strength and direction are linked to the … WebWe now apply the Biot-Savart law (1) to a straight vortex fllament of inflnite length as sketched in Figure 2. The velocity dV~ induced at point P by any elemental segment of the vortex fllament d~l is given by (1). Because the fllament is a straight line, dV~ is perpendicular to the plane deflned by the fllament and the point P. The velocity
