Is it possible to permanently demagnitize metal?

[joedango]

For instance, let's say that i have a piece of metal (ie paperclip, coin, etc) that sticks to a magnet. Is there a way to remove its magnetic properties, so that it can't stick to metal?

Using curie point to demagnetize is only temporary. Is there a way to permanently demagnitize a magnetic metal (the metal can be at room temp. and not stick to a magnet).

Thanks

No.
You have already touched upon one technique to effect "temporary" de-magnetism. Good!
But, I know of no technique to make that "permanent" without a continual outside demagnetizing influence.

What about a http://www.google.com/search?hl=en&...netizer&aq=0s&aqi=g-s1g1g-s8&aql=&oq=demagni", would that work?

Certainly. As long as you are willing to expend CONTINUAL energy to effect a CONTINUAL demagnetization environment it can be done, easily.
As far as some type of "one shot", static situation... NO

The only way would be to melt the metal down and combine it with something that is not magnetic as a whole. Pretty much no. As long as the paperclip or whatever item is made out of a magnetic material it will magnetize.
