seriously, i had no idea.
if u need a strong magnet and have a dead hard drive laying around, take it apart.

the magnets inside a hard drive are dangerously strong

Hmm I have a couple sitting around. I might have to pull one of them apart. I'm guessing you are referring to the heads?
given its small size, you would never expect it to have such a strong magnetic pull.
put it near any metal objects and it will pull it towards the magnet at a high rate of speed.
put the 2 magnets together (comes in 2s) and it would be a struggle to pull them apart, possibly injuring yourself in the process.
what's even more amazing is how the magnetism is canceled by another piece of metal attached to the magnet not much larger than the magnets themselves.
I've never fully disassembled an HD. Sorry I'm not a NERD!!
I couldnt' find any of my old HDs in my box of wires and components, so I'll have to get one out of storage.

I have not fully disassembled a HD either but I do read.
I don't consider myself half the nerd as the majority here. Just figured anyone on anand would know some of these basic things about computers.
Did you know an HD can make music? I have never done it, but I have seen it done.

I guess you missed my sarcasm and me digging through a box of resistors, transistors, caps, etc... looking for one of my old HDs.

i know there are magnets inside an HD. I didn't know they were this strong.
you sir, are the condescending nerd at school that gets your ass beat by bullies after class.

yep, they are very strong.
Not as strong as ones you can buy, like the 35lb variety. meaning it takes 35lbs of force to pull them apart.
If the magnet was oriented towards the platter it would wreck havoc on the data.
Instead it makes the actuator function, that moves the arm back and forth, and also serves as an auto head parking mechanism.
Fun thing to do with these I did last week.
Take a eraser, the big ones that are kind of flat.
Hollow it out enough to pllace the magnet in the bottom.
Glue it in place.
Two things you can do now.
Attach it to metal objects and watch as peopled try to pick it up.
Or my favorite.
Amaze the kids.
Place the eraser on a table top and place the other magnet below the table surface.
Use your 'mind power' to make the eraser move
Oh, and make sure you keep it far away from your wallet.
It can corrupt credit cards in a single pass.

I took apart an old 20gb hard drive 2 days ago. The head was not automatically parked, it was right over the platter!
I put a bunch of steel balls from the wheel bearing off my old car, a 240sx, on the magnet. It's like a dynamic sculpture.
