Find the current I required to establish a flux φ 24 104 Wb in the magnetic circuit of Figure P1314 Here area throughout

 Find the current required to establish a flux φ = 2.4 × 10−4 Wb in the magnetic circuit of Figure P13.14. Here area (throughout) =

2 × 10−4 m2, lab  lef  = 0.05 m, laf  lbe

= 0.02 m, lbc ldc , and the material is sheet steel.

 

 

 

 

b.    Compare the mmf drop across the air gap to that across the rest of the magnetic circuit. Discuss your results, using the value of μ for each material.
