All problems must be worked correctly in order to be eligible for a passing grade in the course. Problem 1 –Analyze/Design of Electromechanical Circuits/Devices Consider the electromagnet shown below. Suppose that b d is very thick, so that the reluctance associated with the top (and bottom) may be ignored. The edge thickness e t is chosen so that the edge area and core area are equal. The winding has N turns; the current in the winding is i . The relative permeability of the steel is r µ . Compute an expression for the electromagnetic force between the upper section of the magnet and the...
