Chemically and mineralogically, the lodestone is magnetite, a massive type of iron ore, an oxide of iron, a mineral related the the brown stuff coating the magnetic disks and tapes used by computers. Magnetite is quite common in nature, while lodestones are relatively rare. This is a real lodestone, making it perfect for science experiments or rock collections.
Please be aware that this is a natural mineral and as such each piece is one of a kind! The one you receive may not be exactly the same as the ones pictured but it will be similar. Price is per each piece. They come in irregular shapes, sizes and weights. Photo shows multiple pieces for demonstration purposes only.
This magnet has a strength of: 50 Gauss (0.005 T)
