I have coils that I have taken out of micro wave transformers ,one coil is fine wire the other is 14gauge and they are wound very tight and I would like to use the 14ga coils in a axial flux alternator but they are larger than the Hugh Piggot design so the magnets need to be larger or multiple . I am wondering if this will work well and how should I arrange the magnets . The coil dementions are 2-3/4"wide OD x4-1/2"long OD x5/8" thick and the hole inside is 1-3/8" ID x3"ID. And can I use the fine wire coil or will they over heat ? the wire is very thin and there must be hundreds of feet in the coil . Thank you for you input . Brian
