Solved: Your hospital is installing a new MRI scanner using a 3.5-H superconducting
Chapter 27, Problem 64(choose chapter or problem)
Your hospital is installing a new MRI scanner using a 3.5-H superconducting solenoid carrying 1.8 kA. Copper is embedded in the coils to carry the current in the event of a quench (see Example 27.9). As safety officer, youre to specify (a) the maximum resistance that will limit power dissipation to 100 kW immediately after a loss of superconductivity and (b) the time it will take the power to drop to 50 kW. What specs do you give?
