[Vwdiesel] Degausing for beginners --( a magnetic idea )

[paulr]

Hagar,

If you're looking for some *really* powerful magnets,
look no further than an old disk drive. Disassemble
the drive. Take the head positioner magnets out -- ONE
AT A TIME. They're shaped something like brake pads (!)
Keep them well separated.

Place each magnet on a smooth table top, far apart.
*Slowly* push one of the magnets toward the other.

At some point, the magnets will begin to move slowly on
their own. Sit back and wait. The magnets will accelerate
suddenly. They'll collide hard enough to shatter.

When I tried it, I was left with shards, and chunks.
Almost impossible to separate the pieces.  Magnets from
the latest, fastest disk drives are even more powerful.

IIRC, GM published a research paper on magnet materials
in them '80's. They were designing permanent magnet starters.
Don't know they ever saw production.  Might be even more
fun.

Time for me to get back on topic.  Enjoy!
