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.

Re the destruction of magnetic data in meteorites by hand magnets, I
wonder whether the thousands of professionally collected fresh Falls,
and professionally collected Antarctic Finds, aren't sufficient for
all the paleomagnetism research that will ever get done? At some point
the relatively small number of such researchers must get saturated
with all the diverse samples they have time to study.
And magnets are mainly used on older finds which, I imagine, must be
less relevant to planetary studies anyway, as they've been on Earth a
long time, exposed to the Earth's magnetic field, and the influence of
nearby lightning strikes, etc., hardly sources of reliable data
anymore. So the worries about this might just be a tempest in a teapot.

Greetings,
I have said for a long time that using magnets to test possible
meteorites or use to show laymen that they attract a magnet isn't
such a good idea as the magnetic field is wiped out.
Scientific studies are and will be deterred. Information we might
have gleaned on parent bodies will have to be determined by other
means if at all possible.
I think there are even webpages that suggest using a magnet to see
if a possible sample is attracted and a form of identification.
We need to change our methods.
