How much toxic chemicals have they inhaled by now?
All of them.

Dude some of those arc flashes on an unprotected eye?
It was so bright it distorted the camera at the source of the arc flash. Not to mention the whole room was washed out with light.
And the dude is like 1ft away starring at it. Holy shit.
Someone on the research listserv at my school just put out a request to borrow a "very large...4x4x1 in N52 magnet (or larger)". I looked it up--if that is truly in inches, it is a 0.3T block of pure neodymium terror. The guy's an MD/PhD candidate. Now what do you suppose he needs something like THAT for?
I use a 2"x1"x3/4" N45 magnet to hold up a camera mount from the other side of the window. The trick is to avoid cracking the window while you're trying to position the mount.Someone on the research listserv at my school just put out a request to borrow a "very large...4x4x1 in N52 magnet (or larger)".

I'm sure it wasn't to test the malleability of the gold Apple Watch!

Woah those magnets could be so dangerous, but I still kinda want to play with some one of those days. A couple of those and some wire would build a pretty nice alternator. They should incase them in wood or something though for experiments like that so they don't get damaged. That's the downside with them is they're kinda fragile. Found that out the hard way playing with hard drive ones... even those comparatively small magnets can do serious finger damage if not careful. Maybe not break bones but they will cause flesh wounds.![]()
Yes they are dangerous and even though they used sticks to push them the bits of shrapnel can easily get lodged deep in one's hindpart for partaking in such a foolish experiment.
A PTFE coating a few mm thick may help a lot if one wishes to do collision-crush experiments.
It would be neat to have a spherical one perhaps 1 meter in diameter and let it roll down a busy street. :twisted:

If you ever buy an island, we're all fucked.
I kind of want to see that now... :awe:
It would be like a cartoon, and start taking cars and buses along with it and just keep going down like a snow ball.

You know what I don't like about you engineers? Always shitting on my dreams.

No worry about that, involves too many helicopters. D:
Of course, IRWC (iron rope) can take down one easily.

(Teflon = name-brand PTFE)
....well, maybe it wouldn't stick to the ball, but the PTFE layer might be sufficiently thick and soft that crushed debris would embed itself in it, permitting additional materials to attach.
Hm, yes, the magnetic field would be unaffected by the plastic. (I somehow managed to forget that the center was magnetized.)Wouldn't the magnetism still keep passing through added ferrite alloys regardless of the initial layer?
Even if the surface is slippery, if the force is strong enough it's still basically sticking to the surface, even if somewhat rotating, right?
It would of course be that much more awesome to see just a giant magnetic ball without coating roll down a hill. :biggrin:

I wonder what it would do to underground steel infrastructure, like pipes and conduit?
Ball down a hill: How about two large magnetic balls rolling down into a valley?That'd make some nice fireworks when they hit.
With proper link placement on Reddit, a Kickstarter for that would likely exceed 5 digits.would watch :awe:
In a big crate. A big wooden "negative" would have to be made to precisely cup the lower half of the sphere to minimize surface stress. Then, the crate has to be skinned with a high perm material (don't know if mumetal would get overloaded by so much flux) to prevent interaction with the environment.With proper link placement on Reddit, a Kickstarter for that would likely exceed 5 digits.
I wonder how big of a spherical magnet you could get with $5k? :hmm:
And then how would you go about delivering it?
It might have to be magnetized on-site.

What was the gentleman who grabbed the cable trying to accomplish? "Pull on cable to signal stop"?
