Can platinum be magnetised?
Platinum is strongly paramagnetic by itself. It is one of the paramagnetic transition metals. ... As you see in my website gemstonemagnetism.com, gems in Platinum jewelry cannot be tested with a magnet , but gems in Gold and Silver jewelry can, as Gold and Silver show no paramagnetic response.
Can you find platinum with a metal detector?

Which metal is used to make magnet?
Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
