Re-magnetizing pickups?

Does anyone know about remagnetizing pickups? I have a few I suspect need remagnetizing. The dc resistance reads strong but they still sound very weak.

What I know so far. Fasten the magnets on each side of a vice. One magnet to have the south polarity facing to the middle. The other to have north facing the middle. I’m to pass the coil between two strong magnets. A few passes will do the trick.

I have the magnets and can determine what the polarities are.

My question is which way to orient the pickup for the pass? If I have north on the top of my pickup, should this point to the north or south of my magnets on the vice?

Any and all insight is appreciated.
 
I think I found the info.

The south of the pickup should face the south side of the vice magnets. The north of the pickups to face the north of the vice magnets.
 
Another way to get it right… The pickup should be attracted to the remagnetizing magnets.

Lindy Fralin has a short vid on YouTube.

Not repelled. If your pickup repels from the remagnetizing magnets, it will demagnetize.
 
I don't know about how one might go about this at home, but...in my lab, way back when... I'd use an electro-magnet to de-gauas tools because electron microscopes use some hideously powerful magnetic fields just to wake up in the morning. Everything in the room would be getting magnetized.

So...find a lab with a transmission electron microscope and just leave the pickups in there for a day or two.

Or head down to a scrap metal yard and ask them to juice your pickup...?

Or...
A tape head de-magnetizing tool...

which is where I was going all along.

An old world tape head de-magnetizer, if turned over, should impart a magnetic field to the poles. And the upside, it's controllable. Should you go too far, flip it over again.

I think. I've never done it. Though I have demagnetized tape heads many-many times.
 
Just wrapping up the thread. @rolandson

I had a fella rewind a pair of flush mount Gold Foils. Actually wasn’t demagnetized at all. The bar magnet was shifted to the treble side such that the E string wouldn’t ‘pick up.’ Simple shifting of the magnet to center fixed it.

I did pass the Neo magnets back and forth a few times for good measure.

Suffered a little water damage. This was a dumpster find.

that'll buff right out, no problem.
