Hello!
I am trying to understand a few properties of the ferromagnetic powder.I could not get the answers to these questions on the web, since any kind of phrasing i used, popped up search results that related to iron powder or ferromagnetic powder, which are manipulated and shape-shift using solid magnets.On the other hand, i am interested only in the ferromagnetic powder properties, in other words:1. Does the ferromagnetic powder have a magnetic field of its own, without a solid magnet being in its vicinity? If it does, what field strength should i expect? Would it be detectable?2. Will a simple non-magnetic metal (that is usually attracted to a solid magnet) be able to attract some ferromagnetic powder on it, if it is dipped in the powder, when there is no solid magnet in its vicinity?3. If i make a ferromagnetic liquid, by mixing it with some kind of paint (there are many videos that demo this on the web), will a non-magnetic metal of the kind mentioned above, attract that ferromagnetic paint to it?4. If the answer to the above questions is no (and also if the answer is yes), if i hold a magnet above the ferromagnetic liquid-paint and leave the magnet above that paint spot until it dries, will the dried paint spot then still not have a detectable magnetic field of its own?Any layman and simple scientific answers or links, coupled with pictures and videos, will be more than welcome!
As mentioned above, i could find only answers that relate to the effects taking place in the vicinity of solid magnets, which is not what i am asking about!Thanks a lot!
