Magnetic Materials - nde-ed.org

Diamagnetic materials have a weak, negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the external field is removed. In diamagnetic materials all the electron are paired so there is no permanent net magnetic moment per atom.

Magnet - Wikipedia

A magnet is a material or object that produces a magnetic field.This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.
