The applications of a ferromagnetic substance are comprehensive. Two-dimensional (2D) materials have attracted increasing research interest because of the abundant choice of materials with diverse and tunable electronic, optical, and chemical properties. Applications of ferrites. Ferromagnetism is caused in ferromagnets and the ferromagnets need to have net angular momentum which is obtained either through the orbital component of the spin component. Some ions and atoms consist of the permanent magnetic moment that may be considered as a dipole that comprises a north pole separated from a south pole. We have shown the various applications and fonctions of magnetic materials in general. Curie point electro-magnets have been proposed and tested for … e.g. The hysteresis curve plays a vital role and it’s of great importance. Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. 5). 8). In antiferromagnetism, the forces between the adjacent atomic dipoles tend to possess signs opposite to that of ferromagnets. Nickel: The chemical element nickel is also found in the earth’s crust and it is represented by a symbol Ni. This type of magnetic arrangement can be found in some elements such as iron, cobalt, nickel, and their alloys. Basically, it is analogous to the electron paramagnetic resonance (EPR). Aibangbee1ands.O. 2. It is invented by Carl Gustaf Mosander in 1843 and it is found in earth crust rarely. In some materials, the permanent atomic magnetic moments have a strong tendency to align themselves even without any external field. The different domains have different directions of the magnetic moment. iew.eu. Ferromagnetic materials or substances are invented by a French physicist Louis Eugene Felix Neel. Neodymium Magnet: It is one type of strong and permanent magnet but it is found in the earth crust rarely and the color of neodymium is silvery white.
