Dear Friends, The great problem lies in here : I have calculated the power requirement of an electromagnet. That Its huge . To minimize this power requirement I would like to see if its possible with super conducting magnet, but I am having a problem, because the power requirement are so low, that it cannot be, and also the turns naturally not valid, Only the Resistance which is very low 1.0e-02x. So having the resistance and the Amperes required using the P=U*I and I = U/R (remember its DC) then the power would be very low, that the amperes are simply not possible in real life. Against this I also happen to know the usual MRI devices uses 50-150 Amperes and some 20-50 volt. This makes some sense but in terms of power requirement still not. A 7-9 Tesla electromagnet have incredible mechanical capabilities as well. So, say I would like to have a magnet which can lift 1 tons from 2 meter. Anybody can help how to calculate this out with superconducting electromagnets?
