Ferromagnetic is a term often used to describe materials that exhibit magnetic properties. However, there are several other terms that can be used as synonyms for ferromagnetic, including paramagnetic, diamagnetic, and antiferromagnetic. Paramagnetic materials are weakly attracted to an external magnetic field and are often used in MRI machines. Diamagnetic materials are weakly repelled by a magnetic field and are often used in levitation technology. Antiferromagnetic materials have two sublattices of opposite spin which cancel out magnetic moments. Each of these terms describes a different type of magnetic behavior, but they all relate to the interaction between materials and magnetic fields.
