The quality of magnetic materials is continually being improved by using increasingly pure raw materials (charge materials) and by perfecting production processes (for example, heat-treating the materials in a protective medium and vacuum melting). Improvements in the crystalline and magnetic texture of magnetic materials make it possible to reduce their energy losses in magnetic reversal, a ...

Magnetic Material - an overview ScienceDirect Topics

Hard magnetic materials are hard to magnetize and hard to demagnetize. High values of both B s and H c characterize these materials and make them excellent permanent magnets. The former establishes the high induction field needed to strongly attract ferromagnetic materials; the latter prevents magnetic effects from being influenced or even destroyed by nearby magnets or external fields. Soft ...

Diamagnetic materials, like water, or water-based materials, have a relative magnetic permeability that is less than or equal to 1, and therefore a magnetic susceptibility less than or equal to 0, since susceptibility is defined as χ v = μ v − 1. Diamagnetic and paramagnetic materials are considered nonmagnetic because the magnetizations are relatively small and persist only while an ...

Magnetic Materials CIE IGCSE Physics Revision Notes

When a magnetic material is placed in a magnetic field, the material can temporarily become magnetised: One end of the material will become a north pole; The other end will become a south pole; When a magnet is held close to a magnetic material, the material temporarily becomes magnetised . This process is known as magnetic induction and results in a force being exerted on the material;

Magnetic 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. This reaction is dependent on a number of factors, such as the atomic and molecular structure of the material, and the net ...

Classification of Magnetic Materials

material responds to a magnetic field and as a consequence the susceptible is a function of applied magnetic field. Therefore, ferromagnetic materials are usually compared in terms of saturation magnetisation (magnetisation when all domains are aligned) rather than susceptibility. In the periodic table of elements only Fe, Co and Ni are ferromagnetic at and above room temperature. As ...

Magnetic Materials: Hysteresis Ferromagnetic and ferrimagnetic materials have non-linear initial magnetisation curves (i.e. the dotted lines in figure 7), as the changing magnetisation with applied field is due to a change in the magnetic domain structure. These materials also show hysteresis and the magnetisation does not return to zero after the application of a magnetic field. Figure 7 ...

Petropedia - What is Induced Magnetism? - Definition

Induced magnetism is the process used to induce magnetism in ordinary pieces of magnetic material by external influence. It is one of the ways used to turn magnetic materials such as iron and steel into magnets. When the unmagnetized magnetic materials are bought near or touch the pole of a strong or permanent magnet, they become magnets. This magnetic character is induced on the objects and ...
