Question

The effective lengths of the core material are as shown. The core is symmetric with respect
to the center leg. The coil has 300 turns with current i=1.5A.

1. Compute the total flux in air gap 1 if the core is infinitely permeable.

2. Compute the total flux in air gap 1 if the relative permeability of the core is 2000

 

Neglect fringing in the air gaps. Express your in microwebers.
