Has a neat force calculator. It shows an interesting relationship if
you pick a geometry and vary the size:
.5 x.5 x.25 in => 9.1 lb in attraction, 5.4 lb in repulsion for a Neo
45 separated by .1 inch. Doubling each time:
1x1x.5 => 57 lb A, 34 lb R
2x2x1 => 277 lb A, 165 lb R
4x4x2 => 1211 lb A, 733 lb R
8x8x4 => 5055 lb A, 3018 lb R
without changing the separation distance.
