   Yeah I think that's OK.   
   If I crank up the current and B field in a SC. magnet,   
   and then put it in persistence mode.   
   (close the SC shunt that allows you to change the current...   
   it's then a closed loop and I can turn off the power supply.)   
   How long will it last?  (assuming I keep it cold and all.)
