"COOL" Mining for .999 Nickel with a Mag Switch.

[henrysmedford]

We just got back from the coin shop and used a Mag Switch to find the .999 Nickel. We just turned it on and found about 20 percent of the coins were magnetic and then dump them into a new tray. After that we could find the .999 Nickel with ease. We just checked this list High Nickel Content Coins to make sure. I have no idea how the Mag Switch works. We can buy junk .999 coins a 6 cents each. Also my wife likes the Mag Switch I had it shipped to my work at first as my wife is sort of a anti-coin-wife. You know all that coin junk in the way. But this Mag Switch is fun to play with.

A must see.--


And this would have taken a long time to find by looking at each coin but we got it in the first pass--

Thanks to member Engineer for this.

I have a couple ideas, but I'm not sure how well they'd work. Does it have a patent number? If so, there should be drawings on google patents.

Look like two--

The mag switch works by using two magnetic disks which either turn the magnetic poles to act together or cancel each other out. Its a pretty neat design.
