Magnetite
overall review score: 4.3
⭐⭐⭐⭐⭐
score is between 0 and 5
Magnetite is a naturally occurring iron oxide mineral with the chemical formula Fe₃O₄. It is notable for its strong magnetic properties, making it one of the main sources of natural magnetism. Magnetite is widely used in industrial applications, as a raw material in steel production, and historically for navigation and compasses due to its magnetic nature.
Key Features
