neodymium magnet

Post by eniam rognab »

hey all, couple weeks back i dropped ~$15 for a 1.75" round 1/4" neodymium magnet. good lord is this thing strong, 42.5 lbs of pull force and 13k8 gauss.

http://www.ebay.com/itm/230936357648?ss ... 1497.l2649

swipe a screwdriver across it to temporarily magnetize it, or what im planning is a magnetizing a metal strip to hold tools ready to go, mount it to a stick and pick up nails and screws after a yard project. i dont know, whatever you need a magnet for these guys have it, cms magnetics.

really a marvel of modern technology, the strength this thing has for its size and most of all weight, its unbelievably light. i figured some of you other geeks might find this interesting! :D im certainly having fun playing science!

Yeah, I have some N52 magnets.

I got them for a maglev turntable plinth idea.

To play with 2 at once invites serious injury.

It is unpossible to push the same poles together.

If you try by hand, one will snap flip, and come together with enough force to cut you badly, or shatter.

2 stuck together can not be separated without tools.

Pickup builders sometimes use supermagnets like this to charge their pickup magnets. Can discharge them too so keep it away from your guitar.

Ok, keep it away from your guitar, your hard drive, your cassette tape, your VHS tape and your tube television.

Better?

Furthermore, pluralize any or all the above if you have more than one.

Also not good to swallow. For external use only. Awful stuff can happen.

If you still have floppy discs, keep magnets away from them too. There's the old office joke about the secretary who kept mysteriously losing data on her discs. Her filing system consisted of sticking them to the supplies cabinet with fridge magnets. How 20'th century. Ah the good old days...

Those suckers are amazing and scary! I fractured a finger within the first week of having them. If two pieces decide to attract to each other, just let em' go and stay out of their way. I'm not sure if it's a valid concern, but I make my son remove them from the house when granpa and his pacemaker visit.

Years ago I worked in a cyclotron lab. Walking by the magnet at the wrong time would surely degauss all the cards in your wallet.

Put neo-mags in the pockets of two people and send them into a crowded room.

How long would it take for them to run into each other? :shock:
