I like magnet from childhood all the times, today I like it as before. Usually, I was attracted by its magnetic force, and used the magnet to do somethings. The chemical component of magnet is Fe3O4 in literature, very commonly. I know the magnetic force is produced by the electron of atom, but how to produce it in industry ?

its very simple i think, for simplicity just take a metallic wire and coil it rigidly!! pass an electric current !! it will produce a sample magnet!! now think if we use this in large quantity in industry!! like running machines parts an all you have to design according !principles of electro magnetic !!!c details in some electromagnetic theories

Thank you for answering this problem. But I was more interested in natural magnet. I know people could produce electric "magnet", and it could bring magnetic force as the same of natural magnet. What I more wonder is how to produce "similar natural magnet",including the same force, structure,figure.
