Luck
Yes MM, I do benefit from reading about inductors. Here is a recent read: http://web.mit.edu/viz/EM/visualizat...es/guide11.pdf Notice equation (11.2.3). It says Inductance = Flux * Number of Turns / Current. Easy to see zero flux means zero inductance. Next page or two is Example 11.3, Inductance of a Toroid.
Ampere's Law is to the Magnetic Circuit as Ohm's Law is to the Electric Circuit. This article has a good section showing how to apply algebraic sum of magnetic potential around a closed magnetic circuit. Opposites Attract: A Review of Basic Magnetic Theories
The luck might come about when something works but not in the expected manner.
