Default Do you konw the magnet material?



Do you know the magnet material? though I am in this industry for one year, I also think the magnet is different to know, there are many many physic things, and with many many data, do you have a good way to deal with this?
thank you for your help.
I am not very clear about the magnet can use to which application.
wish you have a nice day.
Violet Yu

Hi Violet,

What is it that you would like to know? Do you have magnets that require an application? Or, do you have an application that you think requires a magnet, but don't know about magnets?

There are various sector where we can deal with magnets.
Are you talking about natural magnetic field or man made.Clarify your question then I could answer according to question.

Magnetite, a naturally magnetized mineral, has been known since antiquity. The needle of a magnetic compass was made from it more than 2,000 years ago in China. But magnetite is a weak magnet; the magnetic properties of iron are much stronger.

Iron was first used as a magnetic material in the 19th century, after the discovery of the laws of electromagnetism by H. C. Oersted, M. Faraday, and H. F. E. Lenz and after the invention of direct-current machinery by B. S. lakobi, of a transformer and an alternating-current generator by P. N. lablochkin, and of a three-phase current by M. O. Dolivo-Dobrovolískii. Silicon-iron steel was used in electrical engineering after 1900. Nickel-iron alloys, which are easily magnetized in weak magnetic fields and widely used in communications engineering, were introduced not long thereafter.
