I have observed over the years that there are two categories of people when it comes to designing magnetics. First, you have those who know how to build a part. They are usually seasoned engineers, or technicians, who know that there are simple and straightforward design methodologies to ensure success. Secondly, you have the rest of the engineering world who are deeply intimidated by the magnetics. There seem to be endless intractable equations, obscuring the elegant simplicity of ‘how to start a design’.
