AC Magnet / Eddy Magnet

Will a A/C magnet pick up copper?

I do believe my mind has been blown here MDG. How in the world does that work? I thought non-ferrous meant non-magnetic in lamans terms. Please, do explain, be it here or in a new thread. I know a few people are intrigued!

A/c magnet? Wth...that sounds bs to me. If it is non ferrous, then it will not stick. To answer the op q. I throw EVERYTHING in the shred. Including a little garbage, heh, to plastic, to steel. My steel place dont care and I kinda got inspired when I saw they were dumping their office trash in the shred pile. Also sometimes if there is more steel than aluminum, say on a washer transmission, that goes in the shred pile as well. It realyl depends on my mood and if it is worth it to cut apart said item,, or if too time consuming, it goes into the shred.

I really regret it now, but I had like 40 ww1 communications devices. The were steel boxes, with wood encased. The gear being inside. They were too much to rip into, because most of the srews were rotted. So into the shred they went. Took am little coaxing to get the yard to do it, since they had wood around them. But after I mentioned they have possible gold, silver, etc...they were more than happy to take.

Never forget that. Those bastards weighed in at 1825 lbs for 40-5o units. Really makes me wonder what was inside..lol. Just didnt have time or ambition to tear them open, plus storage.

No offense taken scrapette, I googled exactly what you said and it brought me right to this post. Thanks for the idea though!

Same thing as an eddy current, right?

very interesting. I don't think we have to worry about our cheap or free (from microwaves) interfering with our scrapping endeavors !! I don't think 98% of us could afford a magnet that would separate our non ferrous !

Great video. My experience with eddy currents is with metal detectors. The metal detector sends out a radio signal via the coil. The signal strikes a metal object which in turn sends out a signal that is received by the coil of the metal detector.

I wonder if HighVoltage has looked into this technique to seperate copper from the insulation? Mike.

I have two Eriez pan separators, each pan performs a different type of motion. Each magnet has a rheostat where you can aggressively agitate or go to a less aggressive situation where the product on the pan barely moves.

I've only played with the one pan, put the pan on an incline, add some copper, gold and silver then depending on where you have the power set at, the gold will travel up hill until it falls over the edge of the pan into a pail or bucket.

You need to be a bit more aggressive to get the lighter silver to move up hill, to much power on the rheostat and your copper is going to come along for the ride.

Its he same as if you were using a gold pan panning by hand you get to aggressive everything you have in the pan is going over the side.

I'm working on a small eddy current drum which will be approximately 3 inches in diameter, much to small for a scrap yard but just right to recover the precious metals from ball milled integrated circuits. Where your only dealing with about 60 lbs.

My rare earth permanent magnets were recovered from junk stepper motors.

You find stepper motors in photo copiers and printers, larger one from automated machinery like CNC milling machines, lathes and cutting tables. Besides using steppers to make homemade cnc projects you can use them as generators on wind turbines.

Sorry. Glossed right over eddy magnet.

thanks mark the link in american recycler was great wb.

all this is being done by Eddy current.the eddy current effect was discovered by Heinrich Lenz and is called Lenz's law. the wiki page is way to detailed so youtube Lenz's law. links below



http://en.wikipedia.org/wiki/Lenz's_law

and now for your homework.

take a strong magnet and slide it 45 degrees down a thick alluminum plate.
you can feel the force of the eddy currents being generated
hope this gives everyone a bit of insight.

Gus sez "I have two Eriez pan separators...." So I guess that makes you one of the 2% maybe I can start a protest about my envy of your stuff. Miked
