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.

This was my thought as well.

Do you want to be blind? Because that's how you get to be blind.

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?

He wants to observe virtual photons just before going blind? Because that's not how to observe virtual photons before going blind.

He wants to be forever known as the blind pyromaniac? Because this is how you end up with the nickname The Blind Pyro.
 
I have an EMF meter. Would like to see what the E and H fields are on that shit.

I'm digging the cover version to the song Zombie by the Cranberries. LMAO!

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.

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:

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.

If it's PTFE-coated, it won't be a fun game.

(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.

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:

Hm, yes, the magnetic field would be unaffected by the plastic. (I somehow managed to forget that the center was magnetized.)

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.

PTFE was referenced in the original experiment with two brick sized magnets and whatever you wanted to smash in between. Prevents them from getting chipped up and the possibility of getting fragged. Ever had a chip from a bearing race get lodged in your arm or leg? Yeah that kind of hurts. 😀

A bare ass neo the size of a 85cm fitness ball rolling down a steep hill with lots of autos, motorbikes and what not.

Have to wonder if even a contraption such as this could control it at the bottom of the hill!

Heck why not make the poles out of the magnets (they'd have to be center reinforced) as a solid magnet pole would be quite brittle and if shattered by a large runaway bogey, the damage and casualties could be rather high. 😉
 
You know where they play with shit stupidly? Where they have nothing better to do. Rednecks blowing shit up anyone?

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.

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.

5k what? Federal Reserve Notes? 😀

That isn't even going to buy the permits needed much less the collaterals for a set which will be nearly demolished.

$5 million would probably be more like it. 😱

It would probably be easier to steal a beam electrotherapy device, extract the cobalt-60 source and build an aquarium so that the characteristic Cherenkov blue glow can be used to excite some glow fish. While enjoying this marvel, you turn an hour glass (with "sand" made from granules of radium chloride exciting ZnS for good luminous cause!) over and over until they decline visibly or you start vomiting from radiation poisoning, or both. 😵
