An Electrical Circuit Model for Magnetic Cores

In Figure 2, the shape is the same as Fig. I, but the axis labels and values have been changed. Figure 2 shows the characteristic of a specific core made from the material of Figure I. The flux density axis Magnetic Fundamentals: Units commonly used in magnetics design are given in Table I, along with conversion factors from the older CGS system to the SI system (sysfeme infernationalrationalized MKS). SI units are used almost universally throughout the world. Equations used for magnetics design in the SI system are much simpler and therefore more intuitive than their CGS equivalents. Unfortunately, much of the published magnetics data is in the CGS system, especially in the United States, requiring conversion to use the SI equations.
