🧲 Helmholtz Coil Pair Field (2D cross-section and uniformity)

2D cross-section of a Helmholtz coil pair: field-strength map and field lines from a numerical Biot-Savart integral, a movable probe, and the uniformity of the field against coil separation. Same field solver as the 3D page, with four numerical checks.
