An individual measurement location along a scan line. Each scan point records the magnetic field strength at a specific lateral distance from the center of the accessory, all at the same fixed standoff distance from the coil face. The more scan points collected along the scan line, the more accurate the field profile and derived calculations such as flux and gradient.
The field is measured on a grid. Starting at the center, the test engineer steps a probe outward along each axis at a fixed point spacing, taking a reading at every point, and continues a little past the accessory edge to catch the field as it fades. The origin is the center of the accessory surface.
