Plane of core memory

I am the enviable owners of a plane of memory (procured a few years back
at VCF-East, when there were a bunch of 32K? boards int he consignment pile.
(Sorry, not currently interested in selling :-)
But, I am thankful for the links, as I have wanted to interface this
with a CPU or PC of some kind.
A few questions, though:
* Is there a way to "read" the core non destructively using any kind
of passive method (I know, it would be tedious, no doubt, but I just
feel like I should "backup" the core before I go messing with it)?
* Along with the above, might there be a way to extend the passive
read to be a worthy "exhibit" I could take to shows? Core memory is
impressive just to look at, but reading it out using the PC and
displaying the contents is so easy to fake that I think people will
assume the core memory is not really being used. Some way of
showing the actual magnetic changes in a small matrix (the large
plane I have is probably not a good candidate unless there is a way
to show such minute cores fields) would I think make the exhibit far
more interesting, especially if I arranged the grid in a square and
created a really slow version of something like "Tetris" on the plane.
