Against what i have maybe stated earlier somewhere else, the right hand Rule still applies to Coils.
My Example from it, i made me 2 Coils, one CW, one CCW wound,
when you look from an end on the Coil, same Wires and about the same Ohms.
I connected the inner start to positive from the power source, and one showed a N-field at the end,
the other a S-Field at the End. Both Coils been about 15 in / 40 mm long.
The Rule is simple, figure you hold a bottle in the right hand.
Where the fingers point at is the direction of windings, the thumb points at the Bottleneck and the direction from the Pole.
The Northpole here is the one at a Compass, what points to our magnetical southpole (geographical Northpole).
ie. a Coil wound ClockWise create a N-Pole at the end from the Coil, a CCW wound Coil makes a S-Pole at the End.
Maybe it helps someone at designing a Coil, but it usual works too,
when you simple switch the wires, to get an opposite Pole at a fixed Coil.
