Understanding Magnetization

Magnetization is the process by which a material becomes magnetized or acquires magnetic properties. This can occur through various methods such as applying a magnetic field, exposing the material to high temperatures, or using electrical currents. When a material becomes magnetized, its individual magnetic domains align in the direction of the applied magnetic field, resulting in the material exhibiting its own magnetic field.

Types of Magnetization

• Ferromagnetism: In ferromagnetic materials, such as iron, nickel, and cobalt, the magnetic moments can align spontaneously, resulting in a strong overall magnetic effect.
• Paramagnetism: Paramagnetic materials exhibit weak magnetization when subjected to an external magnetic field.
• Diamagnetism: Diamagnetic materials are weakly repelled by magnetic fields.
