A two-legged magnetic core with an air gap is shown in Figure PI- II. The depth of
the core is 5 cm,
Assume a 5 percent increase in effective air-gap area to account for
fringing.
How much current is required to produce an air-gap flux density of 0.5 T?
What are the flux densities of the four sides of the core at that current ?

The reason we can calculate the total flux from the air gap by using the flux density in the air gap is that everything is in series, and the flux that flows through the air gap is the same flux that flows through the
abcd or ad path.
For another circuit, would things be different?
