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.
hehe

Actually, I think the metaphasic shield gets around that problem.
