Chapter 32, Problem 32.73AP
Review. A novel method of storing energy has been proposed. A huge underground superconducting coil, 1.00 kin in diameter, would be fabricated. It would carry a maximum current of 50.0 kA through each winding of a 150-turn Nb3Sn solenoid. (a) If the inductance of this huge coil were 50.0 H. what would be the total energy stored? (b) What would be the compressive force per unit length acting between two adjacent windings 0.250 in apart?

A 10-turn ideal solenoid has an inductance of (3.9x10^-3) H. To generate an EMF of
(1.16x10^0) V what should be the rate of change of the current? Express your result
as the magnitude in A/s.
An air-filled cylindrical inductor has 2600 turns, and it is 2.4 cm in diameter and 34.5 cm long.
What is its inductance?
How many turns would you need to generate the same inductance if the core were iron-filled instead? Assume the magnetic permeability of iron is about 1200 times that of free space.
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 55.0 H, 1.20 km in diameter, would be fabricated. Each winding
of the 150-turn solenoid would be made from Nb,Sn wire and would carry a maximum current of 15.0 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.)
