Question about winding coils.?
When winding coils, will winding the second layer, back over the first layer, in the same direction (for example clock wise) cancel out the coil?
also, i bought a galvaniced threaded rod, thinking it would work as a core. it would work right? What if i had a 8 turn primary. Should it be under the secondary coil. Or could i wind the secondary to the side of the primary?
