What is the shape of the coils for an ideal toroid?

Text Solution

AI Generated Solution

To determine the shape of the coils for an ideal toroid, we can follow these steps: ### Step-by-Step Solution: 1. **Definition of a Toroid**: - A toroid is a three-dimensional geometric shape that resembles a doughnut or a closed tube. It is formed by rotating a circle around an axis that is in the same plane but does not intersect the circle. 2. **Coil Configuration**: ...
