Question 15.7: Calculation of Inductance Determine the inductance of the 50...

In Example 15.5, we found that the reluctance of the magnetic path is

R=4.600 \times 10^6 \mathrm{~A\cdot turns/Wb}

Substituting into Equation 15.25, we obtain

L=\frac{N^2}{R}=\frac{500^2}{4.6\times 10^6}=54.35\mathrm{~mH}
