magnetisoi

Magnetisoi is a term that refers to the process by which a material becomes magnetized, or acquires magnetic properties. This can occur through various means, including exposure to a strong external magnetic field. When a ferromagnetic material, such as iron, is placed within a magnetic field, the magnetic domains within the material align themselves with the external field. This alignment of domains creates a net magnetic moment in the material, resulting in it becoming a magnet itself.

There are two main types of magnetization: temporary and permanent. Temporary magnetization occurs when a material is magnetized only while it is under the influence of an external magnetic field. Once the external field is removed, the material loses its magnetism. This is typical for materials like soft iron. Permanent magnetization, on the other hand, is retained even after the external field is removed. This is characteristic of materials like steel or alnico, which are often used to create permanent magnets.

The process of magnetisoi can be achieved through several methods. One common method is stroking a ferromagnetic material with a permanent magnet. Another is placing the material within a solenoid carrying an electric current, which generates a strong magnetic field. The strength and duration of exposure to the magnetic field, as well as the magnetic properties of the material itself, all influence the degree of magnetisoi achieved. Materials that are easily magnetized are said to have high magnetic susceptibility.
