How to find the Material of magnet

Question

Is there any way to find out if a magnet is a neodymium, ferrite(ceramic), samarium cobalt or alnico magnet (based on color, texture, etc.)?

You might have better luck asking this in Earth Science SE. – relayman357 Oct 04 '20 at 16:28 — relayman357, Oct 04 '20 at 16:28

You might try Xray diffraction.

Ceramics are metal oxides, and do non conduct electricity, while the others are metals.

Thank you for your answer! On the Internet, I find most of the images of ferrite magnet to be dark grey while the alnico magnets to be painted. Is this correct? – Shub Oct 06 '20 at 08:48
