I was wondering if someone could explain why it is that Alnico is considered to be the best pickup magnet material? By this I don't mean "what's different?". I know it sounds different and how it is different, but what I don't get it is why it is so different from ceramic. I've read all sorts of reasons, but most sound idiotic at best. My best example: Kinman claims the difference is because Alnico conducts the single briefly, ultimately coloring it.

I think this will help you out. (rule 3) Dark

Dark,
I read rule #3 and there may be some facts and logic in there worth consideration. But looking at it from the perspective of the pole pieces "sensing" the strings is a misnomer that perpetuates a common misconception. Pole-pieces don't "sense" the strings. They focus a magnetic field on the local area of the strings. The string moving in this magnetic field alters the magnetic field on the coil which "senses" the string.
The fact that the much stronger magnetic field from the ceramic, mounted on the back of the pickup, imparts a strong stationary field on the coil, MIGHT have something to do with tonal differences. But I certainly don't know enough about it to say anything of value here. I suspect having the strongest part of the magnetic field existing behind the pole-pieces, rather than originating from them MIGHT be worth considering as the reason, or at least part of it.
Cheers, Unk
