I've been meaning to do a write up explaining duality in electronic circuits. Specifically in a way you dont hear about covering, for example, the duality between an electric circuit and a magnetic circuit.... I've been knee deep in refreshing myself on mostly the vocab I need to explain this properly and what exactly is a dual and how there are different types of duals that vary what is a dual based on the context, which itself goes back to laplace transforms... man my head is spinning though because im really trying to think of concepts I know well in a very foreign way.
@Feddylain not sure what weird induction circuits you mean, probably not..
It is somewhat related to the fact that the electric and magnetic fields are duals of each other, but goes beyond that. in to a way of thinking most electrical engineers rarely do (and many wouldnt even think is correct)...
Basically in a typical electric circuit wires have low resistance (made of copper) and the elelectric field propagates through it (voltage), and produces current, which has the side effect of producing magnetic fields.
In a magnetic circuit all of that is replaced with its dual. Instead of having a power sorce that produces an electromotive force, like a batter, youd have a power source that produces a magnetomotive force, like a spinning magnet, or a magnet with a collapsing magnetic field... the wires would no longer need to be low resistance, they can in fact have high resistance, but instead would need to have low reluctance. Instead of the electric field propagating through the wires the magnetic field would propagate through it, etc.
Flux flows. Fields change. The magnetic flux flows through low reluctance material (wire?) but reluctance has no dissipative effect on the magnetic current.
@Feddylain dual is a technical proper math term check out ""Pontryagin Duals"
