I would like to know what is(are) the unit(s) of measurement for the magnetic fields of permanent magnets, and what is the instruments for measuring it (if one exists). Thirdly, is there a way to calculate such a field (mathemeticaly, by measurements, etc...)
I have heard of many things...
Specification
Just to say that what I meant by Unchanged conditions was more of something in room conditions (for example, a magnet sitting on a couner... ), not some hypothetical 0 K situation inconcevable in any situation (or almost). I did not specify this because I did not think someone...
