The discussion about the concerns of meteorite contamination while cutting has jiggled a little bell. A few months ago I was talking with Rainer Arlt about meteorites and he mentioned that he was involved with a project that measured residual magnetism contained in fresh meteorites. I'm not sure what that information would tell you, but he was concerned about meteorite hunters sticking a magnet to a meteorite for testing and mess this information up. The residual magnetism from a magnet would leave a residual presence within the meteorite as well. GeoZay
