A steel magnetic actuator shown below is excited by DC with
N=600turns and
I=1.5A. The three gaps have the same length,
x=2mm. Draw the magnetic equivalent circuit and find the flux densities in all air gaps for the following cases. (a) The core material has a relative permeability of
5000(\mu _(r)=5000). Assume the core is laminated by sheet steel and has a stacking factor
=0.8. (b) The normal magnetisation characteristic data of the core material is given in the table below. \table[[H(A/m),100,200,300,400,600,1000,1500,2500],[B(T),0.50,1.00,1.29,1.47,1.60,1.70,1.79,1.86]]
