Greg/Carl:

I have a small NWA 5000 and it sticks to a strong magnet; in fact, I have very few meteorites that do not stick to my magnet: a howardite, Tatahouine (Diogenite) and an Eucrite.? I have been surprized at how many achondrites do have metal in them and do stick to my magnet.? Perhaps that explains why I have boxes and boxes of little black rocks in my garage.
