Answer the following statement true (T) or false (F)
A solenoid having a cross section of 10 cm2 is shown in Figure P18.42.
a. Calculate the force exerted on the plunger when the distance x is 2 cm and the current in the coil (where N = 100 turns) is 5 A. Assume that the fringing and leakage effects are negligible. The relative permeabilities of the magnetic material and the non-magnetic sleeve are 2,000 and 1.
b. Develop a set of differential equations governing the behavior of the solenoid.
