Thank you, Gentlemen.?
I'm still not clear but that says a lot more about my failings than your explanations.
If I lay the binocular flat on the bench with the holes pointing towards me it seems there are two ways to wind it.
1. Start both windings at the end nearest me, pass through and turn both outward, away from each other, Back towards me and then back in at the bottom.
The right hand "tube" is therefore wound clockwise whilst the lefthand is wound anticlockwise.
2. Wind the righthand tube as above but start the lefthand tube from the other end. In this case both are wound clockwise.
I know I might be over thinking this but in the first case the magnetic fields will be opposite whilst in the second they are aligned.?
I appreciate Hans might have allowed for this on the pcb so my question, before I solder it in is still which way should I wind it??
Kind regards
PS I know, I should have done EE not Chemistry!!!
