As far as I have understood your reply, you find two flaws in the analogy. The first is the speed of propagation of the action. You actually say that the air flow can't achieve the speed of the electricity flow.
Let's say we have a torus, a very long torus filled with air. Inside the torus there...
Thank you.
I try to find the principle and this comparison serves pretty good. In finding the principle I don't have to stick imperatively to a coil of wire.
Speaking of coils, here is a comparison for it: when we move a magnet in and out of a solenoid, we can compare that to the "push and spin"...
Consider the following experiment: from a lacquered copper wire we cut off twenty to thirty pieces of about 10 cm. From them we form a bundle of parallel wires and connect the two ends with one more wire each. The other ends of these two wires are connected to a sensitive analog ammeter. We hold...
