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?
