ceramic

I have a custom shop Warwick Streamer Jazzman which I've never quite been satisfied with the tone of. It's made out of bubinga, and I've always thought the sound was quite tinny and dry lacking both the top end "zing" and the rich bottom end that would make it the slap machine it deserves to...

Am I correct in saying that the magnets in my MEC MM pickup are Ceramic? Can't seem to find that information anywhere, but it sounds ceramic. I'm sure there is some simple way to tell visually too, but I don't know what it is.
