Not All Iron Is Magnetic (Magnetic Elements)

2019-7-3  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 only weakly attracted to a magnetic field. Magnetic materials consist of atoms with partially-filled electron shells. So, most magnetic materials are metals. Other magnetic

List of Metals That Are Attracted to Magnets Sciencing

A magnet will weakly attract paramagnetic metals such as magnesium, molybdenum and tantalum are weakly attracted to a magnetic force. The attractive force is about a million times weaker than the force attracting ferromagnetic materials; so you'll never feel the attraction from holding a magnet to a piece of magnesium, for example.
