Is Manganese Magnetic? (Find Out) | Earth Eclipse
It has a lot of carbon but little magnetic material. Between 10 and 14% of manganese is present in manganese steel. The steel becomes harder and more brittle due to the high carbon content. Because manganese is a weak magnet and carbon is also non-magnetic, the final product is non-magnetic manganese steel.

Not All Iron Is Magnetic (Magnetic Elements)
Most people think of iron as a magnetic material. Iron is ferromagnetic (attracted to magnets), but only within a certain temperature range and other specific conditions. Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 °C. Iron is paramagnetic above this temperature and …
