Anybody know what this is?

IMHO these are just indicators for magnetism, like the screwdrivers with voltage indicating lamps inside.
With the scale they can be used to test a batch of magnets for consistency.
The publishing of such values on a website or datasheet is a form of misinformation.

Interesting news on this pickup. I measured the wire on this again. This time to 4 decimal places. It is actually .0014", which according to MWS is 48awg with a single build.

Does anyone have any of this for sale? Buying 5lbs of this from MWS would be insane.

Thanks

That must be a small coil to be using awg 48

I dont even know if the small spools listed have enough wire to fill that bobbin
the others are heavy build

Thanks Copper, Just ordered.

The one I ordered shows about 50k feet, I think it will be enough.

Have a great day!
