In order to get supraconductive properties out of metal you immerse say a coil of copper in liquid helium ( minus 264 celsius yes minus) then you would get a super strong magnetic field with the benefit of not having to sustain an electrical potentiel at that coil.....neet power it up remove the source of energy and forget about it ......well not really because once in a while you have to refill the container that hold the liquid helium and that would be the use of the dewar flask.......And what is the purpose of the SAID apparatus.......Brace yourself....It's a nuclear magnetic resonance spectrometer....yessssss it is used for the analysis of the chemical structure of organic compound by studying the nuclear magnetic moments of molecules or in other words the electron spin. It's a complex technic with complex instrumentation and complex data analysis
So there.....sleep well and stay tune for the next episode

That's a magnet on it's antivibration table. This magnet is filled with liquid mitrogen and used for nuclear magnetic resonance
