Typical magnetic susceptibilities for diamagnetic materials are in the region of ˜˘ 10 5. Paramagnetism Although we stated above that all materials exhibit some diamagnetism, this may be negligible compared to a positive magnetic susceptibility arising from the magnetic moments of unpaired electrons aligning themselves with the applied eld. This is known as paramagnetism. The phenomena of diamagnetism, paramagnetism, ferromagnetism, anti-ferromagnetism and ferrimagnetism (Ferrites) and some of the different magnetic materials are discussed. Magnetic Field Strength or Magnetic Field Intensity (H):It is the externally applied magnetic field. H describes field outside the material. A phenomenon in some materials in which the susceptibility is negative, i.e. the magnetization opposed the magnetizing force. It arises from the precession of spinning charges in a magnetic field. The magnetization is in the opposite direction to that of the applied field, i.e. the magnetic susceptibility is negative (χm File Size: 41KB.

The eddy currents produce a magnetic field of their own which opposes the main magnetic field. Weiss proposed domain theory to explain ferromagnetic behaviour of a ferromagnetic material. As temperature increases this spin alignment is disturbed and magnetization increases. The one of the characteristic feature of the ferromagnetic materials is spontaneous magnetisation i. When a ferromagnetic material is placed in external magnetic field the material get strongly magnetised resulting in saturation magnetisation i. There are two types of electron motions: orbital and spin motion.

Magnetic Field Strength or Magnetic Field Intensity (H):It is the externally applied magnetic field. H describes field outside the material. The two most common types of magnetism are diamagnetism and paramagnetism, which account for the magnetic properties of most of the periodic table of elements at room temperature (see figure 3). Figure 3: Periodic table The two most common types of magnetism . 12/12/ · Types of magnetic materials. There are Five types of magnetic materials. Examples of magnetic materials are: Paramagnetic materials; Diamagnetic materials; Ferromagnetic materials; Ferrimagnetism; Antiferromagnetism; Aluminum, manganese, etc are examples of paramagnetic materials, Copper, water, alcohol are some examples of diamagnetic materials. Iron, Nickle, and cobalt are some examples of Ferromagnetic materials. Magnetic materials can be classi ed according to the degree of similarity with three ideal types of materials: 1) ideal hard magnetic materials, 2) ideal soft magnetic materials, and 3) ideal. Composition in atomic % Oxygen (O2-) is most abundant followed by silicon (Si4+) and aluminium (Al3+). Crust is mostly composed of aluminosilicates. Iron (Fe2+/Fe3+) is most abundant magnetic element. It is 40 times as abundant as all other magnetic elements together. 4.

    I consider, that you are not right. I suggest it to discuss. Write to me in PM, we will communicate.

    It is a pity, that now I can not express - it is very occupied. I will be released - I will necessarily express the opinion on this question.
