Types of materials
A classification of materials, according to their behaviour when faced with a magnetic field, could be the following:
|Type of Material||Characteristics|
Does not facilitate or permit passing of the magnetic Field lines.
Example: the Vacuum
Low magnetic material. If a magnetic bar is placed near it, this will repel it.
Example: Bismuth (Bi), Silver (Ag), Lead (Pb), Water.
Presents an insignificant magnetism. Attracted by the magnetic bar.
Example: Air, Aluminium (Al), Palladium (Pd), Molecular Magneto.
Magnetic by excellence or strongly magnetic. Attracted by the magnetic bar.
Paramagnetic above the Curie point
(The Curie point of metallic iron is approximately 770 ºC).
Example: Iron (Fe), Cobalt (Co), Nickel (Ni), soft Steel.
Not magnetic, even under the action of an induced magnetic field.
Example: Manganes Oxide (MnO2).
Lower magnetic degree than the ferromagnetic materials.
Example: Iron Ferrite.
Ferromagnetic materials suspended in a dielectric matrix.
Example: Materials used in audio and video tapes.
Ferrimagnetic of low electric conductivity.
Example: Used as nucleus inductors for alternating current applications.
