Question

Fring"5
The
have length comparable to the proper air gap length. As a result, the average flux density in the air gap
gap
the effect of frin
flux passing from the core to the air gap cannot remain confined to the air gap but would somewhat
spread out, an effect called fringing as illustrated in Fig. 5.6(c). This is because the flux paths near the air
is slightly less than the flux density in the core, i.e. (B) (av) <B. Fringing can be accounted for empirically
by increasing the linear dimensions of the gap by one-gap length.​
