For magnet lovers...
 

ever since I was a child, magnets have held a fascination for me. I've been
collecting them ever since. It used to be that you could always scrounge
loudspeakers for Alnico magnets. Then when the newer ceramic magnets began
to be incorporated into loudspeakers, it became a challenge to remove them
from their enclosures without breaking them. Now, I have to admit, I am
having a ball collecting the new 'super magnets' - like the ones inside hard
drives. There are also cool cylindrical magnets that you can get from inside
the heads of VHS machines. My question is does anyone know of other sources
either for Neodymium 'duper magnets', or strong ceramic magnets that I may
be missing out on? Magnets like these come closest to being perpetual motion
machines we have yet to make, and I'd hate to have some just wind up into
the trash because I didn't know they were there :-)

Thanks.!

There is a big magnetic iron core if you dig deep enough.
There are stars with an extremly strong magnetic field,
very very strong.
We need a composite (non metal) spaceship.

Take apart a hard drive. There is a pail of magnets in the head positioning
servo. They are very powerful and will pinch your fingers if yo are not
careful.

They are magic, aren't they? Have you tried the drop a magnet down a
copper pipe trick?

For purchase:

http://www.gaussboys.com

has a small assortment.

As you are probably aware, the older the drive, typically the bigger the
magnets. The largest that I've found were from an old full-height 5 1/4"
internal 300 MB SCSI drive. Newer drives are a bit disappointing, their
magnets are getting pretty thin and break easily...

I just tried it with a 1/2 inch copper pipe and a 1/4 inch cube magnet.
Incredible! I did not know it would have that much of an effect!

What a great mental image! I was in need of a chuckle today, and you
came through. Thanks. (BTW, the OP had already mentioned the HD
magnets...)
