Rearranging and solving for μr, we get:

where μ₀ is the permeability of free space and μr is the relative permeability of the core. magnetic circuits problems and solutions pdf

This analogy is the key to solving effectively.

H1=1.2(4π×10-7)×1200≈795.77 At/mcap H sub 1 equals the fraction with numerator 1.2 and denominator open paren 4 pi cross 10 to the negative 7 power close paren cross 1200 end-fraction is approximately equal to 795.77 At/m Rtotal=Ri+Rg=527,851

) of ferromagnetic materials changes with the flux density ( ), leading to magnetic saturation. Step-by-Step Problem Solving Methodology

$$ H = \fracNIl \implies NI = H \times l $$ $$ l = 40 , \textcm = 0.4 , \textm $$ $$ NI = 400 \times 0.4 = 160 , \textAmpere-turns $$ Step-by-Step Problem Solving Methodology $$ H = \fracNIl

. Do not accidentally multiply the air gap reluctance by the core's relative permeability.
