Magnetization is the process by which an object becomes magnetized, meaning it acquires a magnetic field. In most materials, magnetization is temporary and disappears when the external magnetic field is removed. However, there are certain materials in which magnetization persists even after the field has been removed. These materials are called "Hard Ferro magnets".

Hard Ferro magnets are a specific type of permanent magnets that exhibit strong magnetization and retain their magnetism over a long period of time. They are made from materials such as iron, nickel, cobalt, and their alloys. The magnetization in these materials is due to the alignment of magnetic domains.
