Magnetite Facts & Figures | The Magnetite Network

The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4). Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers.

Electromagnetic Induction and Faradays Law

Then by either moving the wire or changing the magnetic field we can induce a voltage and current within the coil and this process is known as Electromagnetic Induction and is the basic principle of operation of transformers, motors and generators. Electromagnetic Induction was first discovered way back in the 1830's by Michael Faraday.
