The toroid in Figure P29.52 has 200 rectangular windings, and the toroid radii are (R_{text {in }}=160

Question:

The toroid in Figure P29.52 has 200 rectangular windings, and the toroid radii are $R_{\text {in }}=160 \mathrm{~mm}$ and $R_{\text {out }}=$ $240 \mathrm{~mm}$. The height of each winding is $b=20 \mathrm{~mm}$, such that the rectangular cross section of each winding is $\left(R_{\text {out }}-R_{\text {in }}\right) \times b=(80 \mathrm{~mm}) \times(20 \mathrm{~mm})$. What is the inductance of the toroid?
