Chapter 3, Problem 3.62P

In Figure 3.59, a 2.0-cm-diameter toroidal core with ${\text{μ}}_{{\text{r}}_{\text{1}}}\text{=10,000}$ is wrapped with a 1.0-cm-thick layer of material with ${\text{μ}}_{{\text{r}}_2}\text{=3000}$. The toroid has a 1.0 m mean radius. For 20. A of current driven through 50 loops of wire, find the magnetic field intensity in each material of the toroid.
