[meteorite-list] Leonard David FYI: damage hand magnets used by amateurs do to meteorites

[John Lutzon]

And the other studies, yet to be conceived, to differentiate between the 
object's original magnetism state

until the moment when it was influenced by our planet's magnetic field. 
Easy solution, go to where they

normally habitat and do such studies in situ. Otherwise, go and find all 
you can.
