Solenoids find application in a variety of electrically controlled valves. The magnetic structure shown in Figure is a simplified representation of a solenoid in which the flux in the air gap activates the motion of the iron plunger.
(a) Develop a general expression for the force exerted on the iron plunger and comment on its dependence on position x.
(b) Determine the current through the coil of N = 100 turns to pull the plunger to x = a, given that a = 1 cm, lg = 1 mm, and the spring constant is k = 1 N/m. Assume the permeability of the magnetic structure to be infinite and neglect fringing.
Digital Systems 1. Describe the working of Binary comparator (Magnitude comparator) a. Define Binary comparator b. Binary comparator working process with logical diagrams 2.
