unity and a small positive susceptibility,
it must be

Answers

Answered by lions094

Answer:

paramagnetic

Explanation:

Because platinum is significantly denser than many of its impurities, the lighter impurities can be removed by simply floating them away in a liquid. Platinum is paramagnetic, whereas nickel and iron are both ferromagnetic. These two impurities are thus removed by running an electromagnet over the mixture.
