Jälkimagnetoituminen
Jälkimagnetoituminen is a Finnish term that translates to "remanence" or "residual magnetism" in English. It refers to the magnetization that remains in a ferromagnetic material after the external magnetic field that caused the magnetization has been removed. This phenomenon is a fundamental property of magnetic materials and is crucial for the operation of many magnetic devices.
When a ferromagnetic material is exposed to a magnetic field, its magnetic domains align with the field.
The concept of remanence is essential in understanding how magnetic storage media, like hard drives and magnetic
