pup magnet I.D.

[popsaka]

How do ya tell the difference betwixt 'alnico' & 'ceramic' magnets, and are ceramics in fact "cast" like fired clay?

thanx in advance

Alnico are metallic and are electrically conductive. You can measure the resistance (low) of the magnet itself.

Ceramics are metal powder sintered in a, um, ceramic medium and are not electrically conductive.

Does alnico not stand for " Aluminum-Nickle-Cobalt"?

I wonder who came up with that combination?

deep,

Near as I can tell, it was done by "engineers" at GE, working on MK-based magnets developed by Dr.Tokuhichi Mishima in 1931. Why those engineers are never credited by name, that's an even bigger mystery.

...and then there was this interesting little link at the top of the page when I was reading this thread....

thanx guys... welly intalesting!

Do yall know if anyone's ever 1.)made a pup successfully using a higher order magnet?(other than alnico or ceramic) ...and 2.) made any contemporary audio devices using electro style magnetics (probably quite noisy!)

1 - Fender SCN

2 - electro style magnetics? I'm not certain what you mean by that phrase. Those three words are not commonly found together in that sequence.

You say to-may-toe, I say to-mah-toe.........

pops is referring to the old style field-coil magnets, which you and I know to have been replaced by permanent magnets, lo these many years agone.

pops,

Yep, we used to use some Rube Goldberg circuitry in the very early days of radio. Needless to say, permanent magents made a whole lot of headaches go away for engineers and technicians.

The only place I can think of right now that you might encounter such devices, in the guitar world, are those sustainer units. Either the hand-held E-Bow, or the pickup-styled sustainer such as the Sustainiac. You might refer to 4pete's thread on the topic of building one of these yourself. Just for your information, you understand.
