Question 7 A magnetic core is shown in Figure 1. Relative permeability of the core is 14 = 2000. Total number of winding turns in the left winding is NL = 100 and in the right winding is Nr = 10. Assume that the core cross section is uniform and the combined length of all air-gaps is much smaller than the dimensions of the core cross-section. Calculate the following: a) The magnetomotive force in the core if i = 2...

Magnetic Circuits y Part A - Calculate reluctances Learning Goal: To understand how magnetic structures can be analyzed by drawing an equivalent circuit, and to use the equivalent circuit to calculate magnetic fluxes and coll currents. When analyzing magnetic structures, the geometry is often complex enough that using the fundamental rules can be very difficult without numerical methods. However, there are approximate methods that are often sufficient for engineering calculations. When the magnetic field is mostly contained within cores of...
