magnetizálódni

Magnetizálódni is a Hungarian verb that translates to "to become magnetized" or "to be magnetized" in English. It describes the process by which a material acquires magnetic properties. This typically occurs when a ferromagnetic or ferrimagnetic material is exposed to an external magnetic field.

The process of magnetizálódni involves the alignment of magnetic domains within the material. In a non-magnetized state, these domains are randomly oriented, resulting in no net magnetic field. When an external magnetic field is applied, these domains begin to align themselves with the direction of the applied field. The stronger the external field, the greater the alignment of the domains, and thus, the stronger the induced magnetism in the material.

Materials that can magnetizálódni include iron, nickel, cobalt, and their alloys. These are known as ferromagnetic materials. Some other materials, like certain oxides, are ferrimagnetic and can also become magnetized, though their magnetic behavior differs slightly from ferromagnetic substances.

Once magnetized, a material can retain its magnetic properties even after the external magnetic field is removed. This is known as permanent magnetism. The ability of a material to become magnetized and retain this magnetism is a crucial property for applications such as creating permanent magnets, electromagnets, and in magnetic data storage. The term also applies to the phenomenon of magnetic induction, where a magnetic field is created in a material by the presence of another magnetic field.
