Magnetic Circuits with Parallel Parts
Magnetic Circuits With Symmetrical Parallel Parts
Consider the symmetrical magnetic circuit diagramed in Figure 1, where the path is of length and area , the path is of length and area , the path is of length and area , and so on.In this case, we can write that the magnetic flux density for the path is:
Magnetic Circuits With Asymmetrical Parallel PartsConsider the asymmetrical circuit diagramed in Figure 2. In this case, due to the lack of symmetry, . There are two methods which allow you to calculate the magnetic flux on each parallel part. The first method assumes that there is no magnetic saturation. The problem is then worked out by using magnetic permeabilities. For a magnetic circuit as the one diagramed in Figure 3, we obtain that: Magnetic Reluctance ). The second method is more of a trial-and-error method. It first implies dividing up the magnetic flux by hinting the right values, and then calculating for all paths. These should be equal, and if they are not, then you have to re-adjust the initial division of the magnetic fluxes.
