I ain't asking, I'm telling!
I used do guitar restoration and modifications to distribute them through schools.
One of the little things I liked to do was change out the ceramic bar magnet and steel pole pieces with alnico poles (you would be amazed at how much an affinity strat improves with those pole pieces and nothing else changed except maybe the strings. Those ceramic magnets are quite useful, I have them all over my toolbox, even inside the engine compartment of a couple of my cars. I use them to hold things.
Since they are somewhat brittle, I can break them into pieces and stretch their functionality. And no, none of them are on my refrigerator.
