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 |

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.

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 did not know it would have that much of an effect! |
