>>14051936>I'm presuming you want to measure the strength of the liquid metallic hydrogen supposed to be at the earth's core?Not really it was just something that popped into my head and I'm fairly bored.
Lets say you had a shell with inner radius 1 meter and outer radius 1.2 meters filled with liquid copper (im assuming conductivity is the relevant metric for this kind of thing, im not genius though) and you could spin this shell 10000 rpm, what would the resulting magnetic field be in teslas?
