Hi All,
I just visited
http://magnetnerd.com/
and saw there the accident page, where a guy got his finger
between 2 very big magnets.
It is very graphic and be warned to play lightheartlywith these
huge Neodymn magnets.
His magnets flew from about 20 inches ( 50 cm) together
and squizzed his finger together and ripped the bones
to pieces !
Okay, now the page...
Only visit it, if you accept to see blood and don´t get
ill from these pictures...

Stay safe and don´t use these big magnets for your first magnet motor prototypes...
Regards, Stefan.
Thanks for the warning Stefan!
But you left off the part about your kind offer to take those mean old behemoths off his hand for a reasonable price....in order to finish that Magnetic beam amplifier you've been working on!
lol

Even small neos can cause serious injury if they get out of control. Small hot pieces can spall off the magnets and strike you in the eye, for example.
I always use a metal jar lid when handling magnets. The lid keeps the magnets bound, and makes them easier to handle.
i agree,watch out ,
...... it happens when you least expect it,holding only 4 small round ones that had formed them self into a bar shape,as i got out of the car they shot right out of my hand and stuck to the side of the car,doh.
...... ,nothing i could have done about it, once i got them off and inside i sat down at the pc and pointed them at the monitor,just to see ....bad idea ..yikes.
... so lowering them between my legs and under the desk it suddenly shot out of my hand again like a bullet making a massive clapping sound and rocking my desk(there was a support bar under there). it took a lot of grunt to get it off and into my closet,a safe place i hope,
....i still havent been able to get them apart for the pulse engine i wanted to make about a year ago.
Oh dear!!! >:(
My thingers have also been between giant magnets, near the same size big monsters as on the picture ... but this time escaped with a blue skin and weals. I ached several weeks after that.
Its near impossible to get free yourself without help of another people ... and this helper must to be how-know-man :'(
Every next step you will do , if wrong idea, causes next and more horrible pain and damages ... if you think to use steel vises - my good !!!! ... you will break fingers or full hand :o
If it happend in workshop wheres lot of steel tools around ... holly wiggle!!!!! ... :o >:(
.... years ago I stored my neo magnets disorganized on the each side of upper steel shelf. Was not very big magnets this time, bigger ones 1"x1"x .5" and smallers .. perhaps
1500 pieces total. And when I got the last shipping via post and on the groaning chair tried to add these magnets between anothers - all this "warehouse" collapsed. I had very tiny
workshop this time, every sq foot was used twice or even more with instrumentarium and self built apparatuses ... its impossible to describe this disaster,
Lot of blood, blue eyes ... broken bottles with paints and chemistry etg ...catastrophe ... cataclysm :D
cheers,
khabe
Use boxing gloves. lol
Won't they separate if you slide them apart sideways b0rg ?

yeah i can get them from 1x4 to 2x2...then it gets hard to the point i dont wanna push it untill i get a work place, like a vice and gloves and clamps,they really are strong little suckers,there about 1cm thick and about 2cm across.
..i saw a utube video ..cd magnet motors and thought if i use bigger magnets,now i see why they use finger nail sized magnets and not golf ball sized ones,there dangerous.
Such hazards are why I always use a remote materials handler for my strong Neos:

This way I get precision placement for my MBAs and Halbachs

My Dad told me a story once about when he worked at Bell Labs in Murry Hill, NJ. (Birthplace of the transistor among other things) He said some engineers were pushing a huge round "super" magnet (almost 3 feet in dia.) down the hall on a shop cart. Well, the walls in that part of the building were clad in steel. (God knows why) they got a little too close to one of the walls and.....WHAM!!!! He said the magnet flew off the shop cart and jumped about 3 feet and stuck to a wall. No one got injured which was very lucky. He said that it took them about a week to figure out how to get that magnet of of the wall. I think they ended up cutting a section of the wall out. Very dangerous, thanks Stefan.

is that your 'remote handler' in the video?

Sliding will usely work. But when the skin of one hand is between 2 magnets it's very difficult to use just the other hand to slide the magnets. Every movement hurts. It is hard not to panic. I know. ;=)
