Unformatted text preview: with a radius of 0.03 m. The two ends are 2 m apart. A flux of 3 mWb enters the large end. A flux of 2 mWb enters the solid through the side of the cone. The B-field leaving the small end of the cone exists in a direction normal to the small end of the cone and is uniform. What is the flux density leaving the small end ? Problem 5 – UI Inductor Analysis Consider the UI core shown on Slide 34/35 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)...
