Magnetization

Magnetization is the process by which a material becomes magnetized, or exhibits magnetic properties. This can occur through various methods, such as exposing the material to a magnetic field or rubbing it with a magnet.

How does magnetization occur?

• Ferromagnetic materials: These materials can become magnetized when exposed to a magnetic field. The magnetic domains within the material align in the direction of the external field, causing the material to become magnetized.
• Paramagnetic and diamagnetic materials: These materials can also become magnetized when exposed to a magnetic field, but the magnetization is typically weaker and temporary.

Factors affecting magnetization

The degree of magnetization of a material depends on factors such as the strength of the applied magnetic field, the composition of the material, and its temperature.

Applications of magnetization

Magnetization is utilized in various applications, including the production of magnets for electric motors, generators, magnetic storage devices, and magnetic resonance imaging (MRI) machines in the field of medicine.
