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 iron attractions toward lodestone. Let us check other important facts about magnetite below:
Facts about Magnetite 1: the rocks
The rocks, which contain small grains of magnetite, are the metamorphic and igneous rocks.
Facts about Magnetite 2: the hardness
The hardness of magnetite is around to 5 to 6 according to a Mohs scale.
Facts about Magnetite 3: the color
Magnetite has the black streak and metallic luster. The color is ranging from brownish-black to black.
Facts about Magnetite 4: the presence of magnetite
The presence of magnetite is spotted in both sedimentary rocks and ingenious rocks. There is no need to wonder that magnetofossils, dentrital grains, and sediments in the marine water and lake contain magnetite.

Facts about Magnetite 5: understanding magnetite
If you want to know more about the formation of rocks, you need to understand magnetite. Hematite is produced through the reaction between oxygen and magnetite. A buffer then will be formed by the mineral pair. The oxidation of magma can be calculated by understanding the compositions of mineral pairs.
Facts about Magnetite 6: magnetic compass
The first form of magnetic compass was created from lodestone. In paleomagnetism, magnetite obtains an important status for its magnetic characteristic.
