You are working at a company that explores new ways of generating and storing energy in an effort to reduce the world's dependence on oil. your supervisor explains a new method of storing energy that has been proposed. a huge underground superconducting solenoid of inductance 45.0 h, 1.20 km in diameter, would be fabricated. each winding of the 150-turn solenoid would be made from nb3sn wire and would carry a maximum current of 20.0 ka.
a. your supervisor asks you to determine the total energy (in j) that could be stored in the coil.
b. she is also concerned about the structural integrity of the coil and requests that you determine the compressive force (in n) acting between two adjacent windings of the coil that are 3.88 m apart. (enter the magnitude.)
