1. Top of WindingBottom of Winding Original spiral wound PF-1 Winding All transitions line up in one direction

2. Splice joint needed to connect a pair of windings Cross-over at top of coil for each winding pair Coil winding approach that minimizes field errors Inside winding pair Outside winding pair

3. Top of winding Bottom of winding For the 4 turn coil transitions cancel on the bottom and leads provide some cancellation on top. Minimum field error PF-1 Winding, 4 x 18

4. Original spiral wound (10 x 8) PF-4 Winding All transitions line up in one direction

5. Top of winding Bottom of winding Minimum field error PF-4 Winding, 8 x 10 For the 8 turn coil transitions cancel on the bottom but line up on the top.
