SUMMARY
The self-inductance of a toroid with a rectangular cross-section can be approximated by treating the windings as a thin homogeneous current layer around the core. In this model, the number of turns, N, is simplified to N = 1, while the current is adjusted to Iapp = Iorg * Norg. This approximation is necessary due to the complex geometry of the coil, which resembles the thread on a screw, complicating direct calculations.
