Fun With Magnets!

I have some 1" cube Neodymium magnets.

I store them outside.

Away from humans.

Far, far away.

Had them in the house for about 30 minutes, during which time my 77 year old father ended up bleeding. Won't go into details. He's a retired machinist, and knows how stuff works. But the magnets were too much for him.

The things are just dangerous at that size. You would think that a you could handle a small pile of 1" magnets.

But you would be wrong.

Run, run away from Neodymium magnets any larger than a pencil eraser. And even those can put you in the hospital.

:eek:
 
The biggest ones I've messed with is 1 inch disc by .25 and .5 inch by two inches (long cylinder). They can catch you by surprise that is for sure.

The thing is you have to think where your hand is and if there is either metal or another magnet near by.

ouch, I leave out the more graphic ones:

I finally found an actual use for a Cold Steel Delta Dart -- it's great for separating disc magnets! :D

You can cut one off a stack with it. That's very difficult to do any other way I tried.
 
Cougar, I was about to make fun of you for having a Cold Steel Delta Dart, until I realized I have one too. :foot:

It's good to know that they're good for something!
 
I worked with some for a design for a test device at nuclear plants. It used about 1 1/4" diameter x 1/4" magnets. Kinda strange, but I made a shield from bronze that directed the force field in one direction for a device that was stuck to a valve to be tested. One day I had one in my hand and another on the table. I had them repelling each other, and from about 6" away, just feeling their strength, and the force was very noticeable. All of a sudden the one on the table flipped over, flew up the 6" and clapped onto the one in my hand, trapping the web of my thumb inbetween them. It took a stainless screwdriver to wedge them apart! Ouch.
 
Hey Guys..

Those big magnets must be a Real bitch to mail

Great way to screw with the Posties though...

They wonder why the box is stuck to the side of their sorting conveyors.

Or ship two really big ones separately in two boxes stacked on top of each other.. One goes to Cali and the other Detroit....Be fun watching them try to pry them apart

LMAO

Would also make an interesting mouse, cat or coon trap!!!

I won't mess with any bigger then 1/4" thick. I have some 1 x .25" disks and even they can be painful. I use thin disks at work to hold chuck keys on the side of our drill press and vertical mills.

The eddy currents they create are kind of fun. We all know that aluminum, brass and copper are non-magnetic, but if you let a NIB magnet slide down a tilted sheet it will go very slowly. If you rub one on an aluminum sheet you can feel the drag. I have some 3/8" spheres that I drop down a piece copper pipe. The also take a long time to fall through.
