Default Magnet stack question



If one stacks a few, say 10, Neodymium Iron Boron (NdFeB)
magnets, 2" by 2" by 0.5" thick, how will the resultant field
compare to that of one of these magnets by itself? Will it be 10
times as strong, or will it be nearly the same as for one single
magnet?

.... probably more than 9, but less than 10 times. But you'll get
progressively less strength with each addition.

Thanks, David. I got into a discussion (argument) with a group of
neurophysiologists and could not resolve the argument.

I was thinking the flux lines through each of two isolated
magnets would simply re-position such that the same number of
flux lines associated with either isolated magnet would pass
through both magnets when they were stacked with the north pole
of one resting on the south pole of the other.

Magnetism is a static force resulting from an array of static atoms with a
suggested polarity;
In close proximity to atoms of a substance of similar nature they do not gain
more magnetism
but will be influenced accordingly, only to their own magnetic power/ influence.
Obviously, the more material matter of magnetism will influence substances in
close
proximity greater than if it was less in space. Try it for yourself!

On the other hand, due to a larger mass of magnetism, the reactance of it to
nearby
substances will increase in proportion. One magnet may lift 1lb in weight in
direct contact
but two may lift 2lb in weight; after a distance of about 5mm, this lifting
strength variable
becomes negligable!
