- Magnetic Material And Their Separators
The nanoparticles of iron oxide are especially cautious because of their fine magnetic properties and size ranging from 1 and 100 nm in diameter. Magnetite is black magnetic material. It is also termed as ferrous ferrite or iron oxide (II, III). Among the overall natural minerals available, it shows the strongest magnetism.
