In the following "semi" table, is a group of magnets,
all seem to have the same Surface field but all different pull force(attraction/repulsive force at maximum with gap = 0).
How is it possibile to have the same S.field rate but different forces? Is it due to the size of each magnet?

X Y A B C D

X = Magnet
Y = Length"
A = Width"
B = Thickness"
C = Surface field (Gauss)
D = Pull force (lb)

Try plotting your pull force versus linear dimension and see what you get. How about pull force versus
cross sectional area?
