Calculate power required to operate superconducting magnet

  1. Mar 16, 2015 #1
    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?

    The power to run these magnets is determined by the power of the refrigerator, not the resistive losses in the magnet.

    thx I look into it.
