The Superconducting magnet for the experimental MRI studies at a laboratory is a 1 m long solenoid of 60 cm diameter, producing a eld of 5 T. The current energizing the device is 250 A.
a) How many turns of this 250 A superconductor are in this magnet?
b) What is the inductance of the magnet?
c) How long will it take to \charge" the magnet to full eld with a power supply providing 1V?
