Can you make a magnet out of stainless steel? Electromagnet?

Question

Do it yourself

For example, I have a stainless steel earring:

It is not taken with an ordinary magnet.
If I wind a coil inside this earring and apply current, will this earring become an electromagnet?

Answer 1

If the magnet is not taken, then it is useless to wind something. Although the coil itself will create some magnetic field. There are grades of stainless steel susceptible to a magnetic field, you need to use them. For example Steel grade AISI 430

Answer 2

No, then the coil will become an electromagnet

Answer 3

It will become an electromagnet, just a coil without a core, when current passes, it creates a magnetic field.
The strength of the magnetic field is likely to be small.

Answer 4

Indeed, to determine why stainless steel is magnetized , it is enough to familiarize yourself with the phase components of magnetic materials. The fact is that martensite and ferrites are strong ferromagnets. Corrosion is not terrible for such materials, but at the same time, the magnet acts on them, as well as on ordinary carbon steel.
