The "Experiments" section is interesting.

especially the experiment:

tab0=Experiments&tab1=Display&id=5

which states the (magnetic) force of attraction is larger than the
force of repulsion. This looks wrong to me, and disagrees with other
experimental results. Perhaps Kopernicky did not switch the two
magnets, and thus the two masses being suspended differ? In the
first experiment the top magnet is being suspended against gravity,
and in the second it is the bottom magnet. It is necessary to switch
the two if they don't have the same mass.
When two magnets are arranged to attract one another the field
lines tend to
concentrate in the volume between them, whereas when they repel one
another the
field lines tend to splay out and fill a larger volume. I wonder if
that might
explain any difference?
I still contend there is no difference in force. Prove me wrong! 8^)
