Magnetism of
Minerals
There are a few
minerals that react when there is a magnetic
field placed near it. There are some that are
attracted to it and there is actually one
mineral by the name of bismuth that is
actually repelled from any magnetic fields.
This is called diamagnetism in which bismuth
is the only mineral with that property. The
minerals that are attracted can be put into
two categories; there is ferromagnetism which
describes minerals with a strong attraction to
magnetic fields and then there is
paramagnetism which describes minerals with a
weak attraction to magnetic fields. The main
minerals that categorized into ferromagnetism
is magnetite(of course) and pyrrhotite. The
minerals that are put into the paramagnetism
are platinum, hematite, and franklinite. The
main reason for a lot of these minerals to be
magnetic is the Fe in there chemical
structures. Below is a video that shows
bismuth propeties between two magnets and how
it repels from each.
