Hi Mike in CO,

Magnetic susceptibility is a difficult question to answer. A CEREGE (CNRS),
Geophysics and Planetologyscientist from France flew out here to Laughlin, NV,
U.S.A. to conduct magnetic susceptibility studies on several of our planetary
pieces including NWA 5000. He spent hours plotting hundred of points on NWA
5000 to create a susceptibility map. All I can tell you is that numbers his
instruments measured were different for each and every point on the rock. I
guess we will have to wait for the results and magnetic map to be published.

If you are asking how attracted it is to a magnet, then my answer is as follows:
NWA 5000 contains more metal than any rock from the Moon discovered, yet a
magnet will barley stick to it unless you are in direct contact with a piece of
elemental metal. I have magnets so powerful that the small amount of iron in
breakfast cereal is enough to make the pieces of cereal stick to them, same for
dry dog food. For the most part, planetary meteorites are not all that
attracted to standard magnets.


I recommend liberating a piece of a suspected planetary meteorite and then
testing it with a magnet therefore preserving the rest of the mass for future
study. A magnet will orient some of the dipoles into a new North South
direction making some future studies impossible.


Best Regards,

Adam

This is probably the 'dumb question of the year' but, is there any magnetic
susceptibility detectable on NWA 5000 or, for that matter any of your planetary
pieces? See, told you it was going to be a dumb question.
