Magnetization

Magnetization is the process by which a material becomes magnetized, acquiring magnetic properties. This can occur through various methods such as exposing a material to a magnetic field, or by rubbing it with a magnet. When a material becomes magnetized, it develops its own magnetic field and can attract or repel other magnetic materials.

How Magnetization Works

At the atomic level, magnetization occurs when the magnetic moments of individual atoms align in a particular direction. When these magnetic moments align, they create a net magnetic field within the material, causing it to become magnetized.

Ferromagnetic Materials

Some materials are naturally predisposed to becoming magnetized, such as iron, nickel, and cobalt. These materials are known as ferromagnetic, and they can retain their magnetization even after the external magnetic field is removed. This property makes them useful in creating permanent magnets.

Study Guide
