magnetizaci
Magnetizaci, also known as magnetization, is the process by which a material becomes a magnet. This occurs when the magnetic moments of atoms within the material align, creating a net magnetic field. Materials can be magnetized in several ways. One common method is by placing them in a strong external magnetic field. This field exerts a torque on the atomic magnetic moments, causing them to align with the field. Once aligned, the material retains some or all of this magnetism even after the external field is removed, becoming a permanent magnet.
Another method is through electrical currents. A moving electric charge creates a magnetic field, and by passing
