I am winding a transformer. I want to get it done right the first time. The transformer has a square core with a coils on opposite legs. I want the polarity to be the same on each coil so how do I wind them? Should the start of the windings be at the top of each coil? Should the direction of the wind be the same for each one? Or since the coils are on opposite legs should each coil be wound in a opposite direction and start at opposite ends?
