I'm always curious at what is a missed link between a work of the coil and of principles of parallel conductors working?
What do I mean?
A. Imagine a coil. It works because of the principle of induction: if a current is flowing through the coil, then there will be a resistance toward the flow, and the current will reach the coil with a delay. So:
"---" - a conductor; "uuuu" - a coil.
The principle of induction of the coil is in her geometry; a coil is constructed as spiral. Before a current reaches the coil there is a force of magnet occurs. In the coil the force of magnetic field gains the current; leaving the coil the current has at least twice more power before reaching it. The coil increase the speed of current just like the wind that leaves a long tube (the fireplace principle).
There's also a work of the magnetic field inside and outside a coil is interesting. It looks like two not proportional tubes surround the coil:
How circles of magnetic field will be placed is depend on a direction of a current.
B. Now a work of two parallel wires. You know, when a current comes in one direction, the wires go from each other in the opposite direction, but when the current flows in the opposite directions - the wires are trying to be close to each other.
C. What am I looking for? I want to find and answer how lines of magnetic forces change when the wires are bending? And how to explain the work of an inductive coil using the principle of B (the work of parallel wires)? There's a little gap: first you know how two wires work with each other, and then how a coil works; where's the principle of working two or more angled or curved wires together?
