Magnetic materials are composed of microscopic regions called magnetic domains that act like tiny permanent magnets. Before an external magnetic field to be applied on the material, the domains' magnetic fields are oriented randomly. Most of the domains’ magnetic fields cancel each other out, and so the resultant magnetic field is very small. Here we derive the expression of this intrinsic magnetic filed, which can be used to calculate the magnitude of the Earth’s magnetic field at the center of the Earth’s inner core. In addition, it is also described a magnetization process using gravity. This is gravitational magnetization process (or gravitomagnetization process) since the magnetization is produced starting from gravity. It is absolutely new and unprecedented in the literature.
