It doesen't make any difference.also when winding multiple layers of same coil.. do all the layers go in same direction(on a horizontally held conductor) EG from left to right.. or alternately.. ?
That's OK; experiment away. Nails work moderately well for electromagnets, if you wind enough turns on them. You can also make a rudimentary motor using nails and a piece of dowel rod.I dont know the value.. but I'm just trying to get the hang of making an inductor for some projects/experiments mentioned here..so was trying it out..
With n-layer coils, direction of wind can become a factor if you have multiple inductors on a board; they will interact with each other. Placing inductors 90° from each other tends to minimize the interactions.also when winding multiple layers of same coil.. do all the layers go in same direction(on a horizontally held conductor) EG from left to right.. or alternately.. ?
Right, as long as the windings themselves go around the core in the same direction, like on a fishing reel. Back and forth doesn't matter.It doesen't make any difference.
