I'm trying to track down a quantitative proof that the most uniform magnetic field between two Helmholtz coils occurs for a separation equal to their radii.
So far I've just been playing around with the Biot-Savart law and proving that B is identical at several trial points along the axis through the centre of the coils in this arrangement, but I can't figure out how to prove it for _every_ point along the axis.
Any help greatly appreciated.
