Those materials which are attracted b a magnet are magnetic materials.Iron, Nickel, and Cobalt are the magnetic substances as objects made up of these materials are attracted by a magnet.Also, magnetic materials can be magnetized or we can say that magnetic materials can be converted into magnets.
Magnetized Ferromagnetic Material.By applying an external magnetic field to the domains of un-magnetized ferromagnetic, the domains will rotate and aligns in the direction of the magnetic field, because of the domain character of ferromagnetic material even if a small magnetic field is applied gives rise to large magnetization.
1 The permeability of natural materials is caused by either the orbital or electron spin magnetic moment.Of the two, the electronic spin magnetic moment is much stronger and when present and uncanceled is the source of observable magnetic properties.
4-130 MAGNETIC SUSCEPTIBILITY OF THE ELEMENTS AND INORGANIC COMPOUNDS When a material is placed in a magnetic field H, a magnetization (magnetic moment per unit volume) M is induced in the material which is related to H by M = κH, where κ is called the volume susceptibility.Since H and M have the same dimensions, κ is dimensionless.
= Susceptibility (Parameter to access magnetic ability of material) Value means be positive or negative .Higher positive value, better is the magnetic quality of material .Classification of Magnetic Materials: Magnetic materials can be classified as: 1.
All types of materials and substances posses some kind of magnetic properties which are listed further down in this article.But normally the word “magnetic materials” is used only for ferromagnetic materials ( description below), however, materials can be classified into following categories based on the magnetic properties shown by them: 1.Paramagnetic materials The materials which are .

Ferromagnetic materials are strongly attracted by a magnetic force.The elements iron (Fe), nickel (Ni), cobalt (Co) and gadolinium (Gd) are such materials.(See the Periodic Table in the Chemistry section for more information on the elements.The reasons these metals are strongly attracted are because their individual atoms have a slightly higher degree of magnetism due .
Ferromagnetism is a kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements.It also occurs in gadolinium and a few other rare-earth elements.In contrast to other substances, ferromagnetic materials are magnetized easily, and in strong magnetic fields the magnetization approaches a definite limit called saturation.
The magnetic anisotropy in effective magnetic materials, which surfaces from the arrangement of magnetic moments under external field, can be developed at different structural scales.Magnetic patterning, magnetic ordering, and text ration are at the beginning of this anisotropy development.
In order to classify materials as magnetic or non-magnetic, it must be determined whether or not forces act on the material when a material is placed in a magnetic field.If a bar of any given material is suspended in a magnetic field, it will either turn at a right angle to the field or align with the field.
Jan 05, 2016 Types of Magnetic Materials.To study magnetic properties of magnetic materials, the material is usually placed in a uniform magnetic field and then the magnetic field is varied.There are three major kinds of magnetic behaviour: Diamagnetic materials .These materials are barely magnetized when placed in a magnetic field.
