Question

Can Fe3O4 (magnetite)used as a magnet

Answer 1

You can use it but as particles are highly magnetic and stick to the magnetic bead leads to the problem in mixing .........

Its better to use a non magnetic stirrer stirring with external triangular shaft made of teflon so that mixing continues without sticking to teflon

Answer 2

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.So yes it can become a magnet.Hope this helps you.
