How to judge whether a metal material is non-magnetic or magnetic? Such as stainless steel, what testing instruments?
With a magnet suction you know, can be a magnet sucking is a magnetic material, which cannot be attracted by magnetic material is non magnet.
Such as stainless steel, iron alloy is inevitable, so there must be a magnetic material, magnetic material, but I don't know whether you said it is magnetic, if this is the case, there must be a permanent magnet magnetizing the magnetic, soft magnetic material is not magnetic, simple experimental materials can be used close to the pin, if can suck, prove the existence of some residual magnetic materials!!!
The simplest judgment!!! Does your material contain iron, nickel, cobalt?.
