Magnetizáltságot

Magnetizáltságot, often translated as magnetization, is a vector quantity that describes the extent to which a material becomes magnetized. It represents the density of magnetic dipoles within a material. When a material is placed in an external magnetic field, its constituent atoms or molecules, which possess magnetic moments, tend to align with this field. This alignment, or the induced magnetic moments, contributes to the overall magnetic behavior of the material.

The magnetization vector, denoted by M, is defined as the total magnetic dipole moment per unit volume of the material. Its unit in the International System of Units (SI) is amperes per meter (A/m). Magnetization is a crucial property for understanding how materials respond to magnetic fields. It is particularly important in the study of ferromagnetism, paramagnetism, and diamagnetism.

In ferromagnetic materials, such as iron, magnetization can persist even after the external field is removed, leading to permanent magnets. Paramagnetic materials exhibit a weak magnetization in the direction of the applied field, which disappears when the field is removed. Diamagnetic materials are weakly magnetized in the opposite direction to the applied field. The relationship between magnetization, the external magnetic field, and the material's properties is often described by magnetic susceptibility, which quantifies how easily a material can be magnetized.
