  • Brain Magnetite - THE SEDONA EFFECT:

    Magnetite is a black mineral form of iron oxide that crystallizes in the cubic or isometric system, namely all crystals which have their crystallographic axes of equal length at 90 degrees to each other. It is a mixed Iron (II) Iron (III) oxide, Fe3O4, and is one of the major ores of iron that is strongly magnetic. Some varieties, known as lodestone, are natural magnets; these were used as

    Find the details about a mineral on Facts about Magnetite. Fe3O4 is the chemical formula of magnetite. You can turn magnetite into a permanent magnet if it has been magnetized before. A magnet may attract magnetite due to its ferromagnetic characteristic. Lodestone is the naturally magnetized pieces of magnetite. The property of magnetism was discovered by the ancient people for the first time due to

    Tiny crystals of magnetite are present in many rocks. In the crystallization of an igneous rock, tiny crystals of magnetite form in the melt, and because they are magnetic, they orient themselves with the direction and polarity of Earth's magnetic field. This preserves the orientation of Earth's magnetic field within the rock at the moment of crystallization.
