Don't speak, I believe you must have strange.
In our life can be seen everywhere around the existence of the magnet, electronic products, machinery and equipment, and so on.
Then there is a small problem, the magnet is how to form?
This time we have to understand a substance that is called magnetite.
Magnetite is a common accessory mineral, scattered in a lot of igneous rock.
In some of the rocks, it is because of magmatic differentiation and segregated, and forms the huge iron ore body.
Some contain ilmenite deposit often.
Magnetic titanium ore often appeared in the metamorphic rock is huge bedded and lenticular ore body.
The world's large magnetite deposit is Sweden's luna and gayle, the deposit is thought to be segregated from magma.
And magnetite in China are mainly distributed in Inner Mongolia baotou and ganzhou in jiangxi province, is a rare earth magnetite, is also very strong magnet in the world, accounting for 80% of the world's rare earths.
In the current era of rapid development, the role of the magnet is self-evident.
In view of the relations of time, about the content of the magnet is learned here first!
