Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â* Mikek 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*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*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. file:///C:/Users/Lamont/Dropbox/contra%20wound%20coil%20with%20flux%20and%20curren t%20flow.jpg Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â* Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â* Mikek 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. Â*I should have added more information. The coil(s) are put in an electromagnetic field, creating a magnetic field around the coil. the magnetic field creates a current in each coil. what is the direction of each of those currents? https://www.dropbox.com/s/c4k2hh4syd...0flow.jpg?dl=0 Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â*Â* Â*Â*Â* Mikek PS, it took me hours to get this understood and now, it's like, well ya! Ok. You have all the answers so go with that. Good luck. |
