A Brief Overview of the Diverse Uses and Properties of

Magnetite is an important material component of power plants as it is used to generate electricity. Magnetite, owing to its magnetic properties, is widely used in compasses and other navigation devices. Magnetite also serves as an excellent abrasive which is a cleaner and has way lower toxicity than abrasives that have a silica base.
