Well my cousin called me the other day to see why his computer was not working. I went over and tried to start it up but it would not boot. Thinking it might be the RAM I went to open the case. Low and behold right side of the case is covered in magnets?????? Ask him what the hell would he put those there for, and he tells me his wife collects the magnets and there was no more room on the fridge. Ok lets take them off... I get to one magnet I can't pull off the damn case, looks like a thick washer, kind of a polished hematite look. He tells me it is a rare earth magnet (whatever the heck that is) they got at a science store. I literally had to slide it off the side of the case(damn difficult) then it sticks to the back, skuff up my fingers but with a pair of pliers I was able to pull it off. As a note to all, computer cases are not a good place for your magnet collection.

By the way that magnet can pick up 100 lbs. pretty easy

I was going to say: Only the most very, very strong magnets can actually effect a HDD or Credit Card, etc.

But, then I read
Quote: "rare earth magnet"

And realized you were talking about one of these very strong magnets

Sounds like he's messed up big time!

If it's like the ones we had at the hardware store it could pick up as much as 250lbs. And definitely wipe a HDD

i'm pretty sure magnets can mess up LCD screens too, if you touch one to it

(either that or CRT, i don't remember which, but one of my friends had a spot on his screen where he tried out the theory lol)

That would be a CRT, which can be fixed sometimes by degauss'ing a lot, or using one of those demag wands.

Magnets do a couple of things to CRT TV screens- one is to magnetise the "grid", which is repairable. But if it manages to move the screen's coating around too, you are pretty much screwed. I don't see the same problem happening with LCD screens, although it may damage them in a different way.

Well... I don't know what to say. I learned my lesson once when I was about 6. I was playing with a magnet and my dad came home and well... He got mad.

I don't suffer from laziness... I enjoy every minute of it!

I used to have a VHS magnetizer, it was a block with an electro magnet that allowed you to put a VHS tape on it and it would wipe the contents. Funny enough I tried it on a floppy disc years ago and it corrupted the floppy as well. 5.25 inch disc btw

It can be worse too. A long time ago I sold a computer to a couple and everything worked fine at my house but the minute it was at their house the monitor was flickering like crazy. The only thing I could come up with was an electromagnetic field from the houses wiring that was causing the monitor to go haywire.

Are you sure they didn't drop it on the way? "Flickering like crazy" isn't something an electromagnetic field commonly found in a house is capable of.

I love the trick of making a call on your mobile, then holding it next to your CRT... The interference is crazy!

I remember the days of floppy disks...get a magnet near one and you're screwed.
I was under the assumption that everyone knew that computers and magnets don't go together.
You did explain to this poor soul's wife why she couldn't put magnets on the computer...I hope.
And just how many magnets do they have anyways?We have a boatload and the fridge still isn't covered with them.

I'm pretty sure it was me that brought it to their house... I'm not 100% sure though.

Nope, told him to take it to a computer shop, as I would have nothing to do with it after that. I did advise him that attaching a pair of jumper cables to his balls is also not a good idea, figured if he could do this he meight do anything.

She was not home I left it up to him, she is a complete MORON though, she could not spell CAT if you spotted her the c and the t.

OMG, its insane how many they have, but I understand large collections, I have thousands of Warhammer and 40k minatures, about 50 long boxes of comics, and 80k + MTG cards. However I do wonder just how many WWJD magnets one person needs.

They need to just take sheets of metal and attach them to a wall. That way the fridge too is left alone.

Actually this reminds me of an interesting article on Slashdot.

If you're a CIA or other government agent and you have hard drives and laptops with sensitive info, and your plane is going down in the jungles of North Korea, what do you do? You could take an axe or a gun to the drives--- but noo--- the data can still be recovered. The absolute fastest and best way to destroy data so it's unrecoverable is placing a large magnet on the drive for a few seconds. And I believe that's what they've been trained to do.

Perhaps the reason the plane went down in the first place was due to the high-powered magnets screwing up the plane's instruments?

i thought i'd destroyed a CRT monitor with a powerful magnet
everything appeared all screwed up for ages

i was experimenting with making the colours change with the magnet
and was gutted when i took it away and it stayed the same

it fixed itself after a good while though
