what is the average size of a domain?
and how are "permanent" magnets made?
Permanent magnets are made from a mixture of elements usually iron and nickle or cobalt. Iron isn't a good permanent magnet, if you have an iron magnet then just droping it may make it scatter into different domains, therefore you try to mix it with weaker but more stable magnetic elements. I don't quite understand what you mean by the average size of domians, to my knowledge there is no specific sizes in which domians come in.
thanks. my teacher asked us to find the average size of domains, and i honestly looked everywhere i could think of and couldn't find anything.
