I'm thinning down my collection of magnets. These are extremely strong N50/52 rated Neodymium magnets.
You can look on youtube for all the crazy things these are capable of, or cool projects that you can make.
You can try to look on Google to see what these magnets normally run as well. These are very uncommon, and are made specifically for industrial applications.
I purchased them at a reduced price from an industrial setting. Now I am trying to recoup some of my money.
I am located in Charlotte, and my prices are OBO. I will be willing to move more on prices when you buy larger magnets or quantities. I would prefer not to ship these.
The prices below are copied from my thread on a different forum. I'll do a TWW discount from those.

I have the following magnets available:

2- 4''x1'' pucks
These retail for $650 a piece.
Each magnet has a contact pulling force of 700lbs.
I would like $125 a piece for these, $200 for the pair

3- 3''x1'' pucks
These retail for $350 a piece.
Each magnet has a contact pulling force of 300lbs
I would like $100 a piece for these, or $225 for all three.

8- 1.5''x.75'' donuts
These retail for about $35 a piece.
Each magnet has a contact pulling force of around 40lbs.
I would like $10 a piece, $30 per 4, and $50 per 8

3" Pucks:

I'd like to hear more about this magnet collection

There is nothing exciting. Just have a lot of them, and they don't really have a purpose.
Some of them I bought with the intent of 'modern art' type applications, and some to make toys out of.

There are cool motors and catapults that can be made with these, as well as the 'levitation' properties.

...and serious injury with the right conditions?

Any of the pucks are capable of crushing all the bones in a hand or fingers if the user is not paying attention.
Most people recommend wearing welding gloves when handling them. Not to protect the bones from crushing, but to be able to remove your hand once the magnets are stuck together with you hand in between.

whoa what happens if you accidentally let them touch? is there a practical way to separate?

11/28/2012 7:29:45 PM

If you slide them together, then nothing really happens. They are just stuck together really well.
You use the box that the 4'' puck is posted in for the base magnet, then use a wooden wedge to slide between them and make distance. Then you slide them apart horizontally.

There are safety videos and how-to's on youtube about these type of magnets.

For the 4" pucks; at 3 about inches, there is about 40lbs of pulling force. The closer the magnets get to each other, the stronger the pull.

I can imagine only horrifying results from mishandling these.

11/28/2012 11:59:56 PM

Would you be willing to donate any of these magnets for classroom use?
