A very large, superconducting solenoid such as one used in MRI scans, stores 1.00 MJ of energy in its magnetic field when 105 A flows. (a) Find its self-inductance (in H). H (b) If the coils "go normal," they gain resistance and start to dissipate thermal energy. What temperature (in °C) increase is produced if all the stored energy goes into heating the 1070 kg magnet, given its average specific heat is 200 J/kg-°C? °℃
