Unformatted text preview: uniform. What is the flux density leaving the small end ? Problem 4 – UI Inductor Analysis Consider the UI core shown on Slide 36/37 of your Lecture Set 1 lecture handouts. Consider the following parameters: 1 = w cm; 5 = s w cm; 2 = s d cm; 5 = d cm; 1 = g mm; 100 = N Suppose the material used is such that for a flux density less than 1.3 T (the saturation point), the magnetic material is linear and has a permeability 1500 times that of free space (i.e. a relative permeability of 1500). What current will result in a flux density of 1.3 T ? (In other words, if we call this the point of magnetic saturation, what current will saturate the core) Problem 5 [EE595 ONLY] – Review of lineintegral and application to MMF drop. Consider a Cartesian coordinate system on a plane (the plane lines on the x and yaxis). A current of 100 A is flowing up out of the plane at the origin. Find the MMF drop between the point x=1,y=0 and the point x=3, y=2....
