Magnetic materials

The diamagnetic field produced by the material opposes the external field, but, except in superconductors, this diamagnetic field is very weak If the atoms of a material have no magnetic moment of their own then diamagnetism is the only magnetic property of the material and the material is called diamagnetic Copper is such a material...

Magnetic Materials

Diamagnetic, Paramagnetic, and Ferromagnetic Materials When a material is placed within a magnetic field, the magnetic forces of the material s electrons will be affected This effect is known as Faraday s Law of Magnetic Induction However, materials can react quite differently to the presence of an external magnetic field...

Diamagnetism physics Britannica

Diamagnetism, kind of magnetism characteristic of materials that line up at right angles to a nonuniform magnetic field and that partly expel from their interior the magnetic field in which they are placed First observed by SJ Brugmans 1778 in bismuth and antimony, diamagnetism was named and studied by Michael Faraday beginning in 1845 He and subsequent experimenters found that some ....
