Pyrite crystal has an extremely high iron content, which means it is naturally magnetic and would indeed stick to a magnet within close proximity. There is always the possibility of encountering weaker forms of pyrite that did not form with enough iron inclusions to offer magnetic ability, however this is extremely rare.Web

Pyrite roasting leads to magnetic sulfide (e.g., pyrrhotite, F e 1-x S, 0 ≤ x ≤ 0.125) and iron oxide (e.g., Fe 3 O 4 and Fe 2 O 3) formation (Huffman et al., 1989). The conversion of pyrite into magnetic sulfides can be realized by a short roast in air through a chemical change similar to Equation (3) .Web
