    measure magnetic attraction versus distance

    What I expected: what you find in literature: like Newton's gravity law : F :: 1/r^2. Or if you prefer to express that different: In a rotatory symmetric system {\nabla\cdot B == 0} everywhere, the same since there is no source or sink of B outside the magnets. On log-log paper that gives a...
