BiotSavart for Mac

From Ripplon Software Inc.:

BiotSavart calculates the magnetic field resulting from general 3-D configurations of current-carrying conductors. It has proven useful in the design of superconducting and copper coil systems. Conductor types include current loop, thin and thick solenoid, racetrack coil, and filamentary wire of arbitrary path. The magnetic field can be calculated along any path and graphed; or on any plane surface to give a contour plot; or in a volume to produce level-set or arrow plots. Field plots are updated as you modify the conductors.
