Magnet Question

Is there any way to distinguish between A2 and A5 bar magnets by some measurement or physical attribute?

Re: Magnet Question

I don't know where you got them, but all the A2 magnets I've pulled out of Duncan pups have had a blue marking on one edge.

If you have two mags and you know one is an A2 and the other an A5, the fridge test is alright. Put both mags on the fridge and the one that's consistently harder to take out if the A5.

If you have mags with no markings, it's going to be difficult, even with a Gaussmeter, as fx, A4 and UOA5 bars read very similar, just as A2 and A3.

So, there's no simple answer for your question.

Re: Magnet Question

Both of your answers are extremely helpful although I'm feeling a little bit foolish right now. I just looked closely (for the first time) at the magnet in question .... looked to find a blue mark per Kam's suggestion. Instead of a blue mark I found this mysterious, possibly hieroglyphic inscription: A5

Re: Magnet Question

Is there a way to test the magnetic strength of a pickup? I'm thinking of pulling a ceramic bar magnet out and replacing with a couple small Neo mags. I know Neo are stronger, but they are also much smaller. If they are too strong, I could also put a shim in and "air mod" them. I just need a way to test the actual strength, preferably a quantitative approach rather than a fridge test.
