Hi all,
If you put two coils on one form, but wind one in the opposite
direction, Do the currents flow in opposite directions?

PS. opposite winding direction as in clockwise or counter clockwise,
Â*Â*or like a left hand and right hand thread.

If it is a continuous coil with only two connections (start to finish)
but winding is reversed in the middle of the coil, the current does
not reverse.

Â*That wasn't what I ask, but since I posted I did put an answer
together. It took me several drawing to get to a final answer that makes
it so simple I don't know why I ask the question. I took me several
hours to come to the conclusion though.
Â*My answer to your question would be, the current does reverse and for
your example, the current would be very low. Probably not zero because
of time/phase concerns.

I have one drawing showing a coil and the right hand rule that gives the
answer.

The current can not reverse in a series connection. But the magnet field
can reverse in the two series windings if one of the windings is reverse
wound.
