magnetizáltak

Magnetizáltak is a Hungarian term that translates to "magnetized" in English. It refers to the state of a material that has become a magnet, meaning it possesses a magnetic field. This can occur through various processes.

One common method is exposure to a strong external magnetic field. When a ferromagnetic material, such as iron, is placed in such a field, its magnetic domains (regions where magnetic moments are aligned) tend to align with the external field. Once aligned, the material retains a degree of magnetism even after the external field is removed, becoming a permanent magnet. This process is often used in manufacturing magnets.

Another way to magnetize a material is by passing an electric current through a coil wound around it, creating an electromagnet. This induced magnetism is temporary and disappears when the current is switched off. However, if the material is ferromagnetic, it can retain some residual magnetism.

Magnetization is a fundamental concept in physics, explaining phenomena like attraction and repulsion between magnets, the operation of electric motors and generators, and magnetic storage devices. The strength of the magnetization depends on the material's properties and the magnetizing process.
