Strongest magnets you can buy?

What would happen if someone shot a bullet through the magnetic field of one of those super magnets?

Was wondering that also. Depending on strength of field and speed/mass of the bullet, it may change it's trajectory. If field is very strong and bullet is light and slow, it may stick to the magnet.

Hmm, didn't know bullets were made from steel...I thought it was lead

You're right...lead and copper won't be attached.

edit: some bullets have steel jackets

I ordered a couple of the rare earths for setting up a cheap, quick hall measurement system. Two magnets came with about 150 lbs surface pull each, separated by about an inch of cardboard sheets. Getting those two magnets apart was scary. They really want to pinch.

The good ones do...

The cheap ones have alinco magnets. :roll:

At least, I'm pretty sure. If its a neo, it was rather weak.. and the finish wasn't smooth. It looks like an alinco magnet.

I got one for free and just ended up taking it apart to investigate.. lol

They didn't even use Schottkys. 🙁

Seems like for less than $1000 one can get 3 #33 magnets for unbelievable strength. Woo!

Also, how do you make a rail gun?

yes, how do you make a rail gun?

Good job not reading through the post before posting there.

Strong magnets are used in many hybrid cars, I remember being told about a Toyota mechanic that lost his hand working on one because he didn't use the special tool to hold the engine transmission/motor apart when servicing it and it snapped back together.

Place magnets on the bottom of your mouse.
Then make a mouse pad out of something magnetic with like charges of that of the magnets on the mouse.

The two repel each other making a completely frictionless mouse.

You've been beaten to it:

Looks like a wobbly POS.

Anyway, an 800 lb pull magnet sounds absolutely lethal. God, I want one. But I know I'd end up being decapitated the first day I recieve it.

You take a regular gun and you put it on a train car.

What amount of pull are the magnets inside a regular 3.5" HDD? Those are about the strongest I have messed with, and I'm sure they aren't even high on the scale.

Good thread. Saved for mischievous purposes later on. 🙂

You have a dirty mind, lady.

Dirty minds are the best kinds. 😀
And I totally called it (not that it matters) - the Asian guy had the smallest flashlight. Oh well.

So what's the women's flashlight look like? Does it just have a little bump that gets moved back and forth repeatedly? Or is the magnetic assembly worn on the finger, and then...um, repeatedly "run through" coils of wire lining the inside of the flashlight? Hmm, I think I'm going to need some R&D money. And volunteers.

Sounds about right. I haven't seen any "U" shaped magnets anywhere yet either. I guess those were faded out around the 60s or something.

Again, how could they possibly ship an 800 pound magnet?

Very carefully.

Headlights...

And while your mind is in the gutter check out the ring magnets on that page that are to be worn around a finger or...

Then cue up some Walter Egan and check your charge. 😉

I like the way you think... 😉

I gotta take that broken 120gb Maxtor apart...😉

So if you can't carry a magnet through a room with electronics or within 10 feet of metallic objects, how the heck do you ship it? It would get stuck to or break other objects. It would interfere with the computer in whatever vehicle is moving it. Or it would get stuck to the vehicle moving it.

Single magnet on a wooden horse-drawn carriage?

That's what I'm wondering too. Anyone have an answer to this one?

They probably ship them in a steel box, which will severely curtail(though not eliminate) the magnetic flux. They'd probably need several inches of solid wood for the packing material to keep them from sticking to the box, though. Some of the pics on the unitednuclear site show them in wood boxes.

yup, decently sized and reinforced box is probably enonugh. magnet strength rapidly drops with distance.
