Interesting. Now that you reminded, I think there are still some neutral coil adjusting tools down in the workshop, left over from the radio says. I'll dig one of those out and test it on XRF. for fun.
If you still have your supermagnet, handy check the ends of the wire vs the sides of the wire with it. There seems to be a dramatic difference. See the video clip:
