Is Gold Magnetic? | Physics Van | UIUC

Shawn - Pure gold is not magnetic. That is, it doesn't form a magnet on its own. If you put it in a magnetic field it will magnetize a tiny bit, but only so long as it's in the field. and the direction of the magnetizaqtion makes it weakly repel the magnet. There are alloys of gold, for example gold with more than about 20% of the atoms replaced by iron, which do …

Need insight on processing magnetic Gold filled wrist watch tops

I'm getting ready to process a batch of magnetic gold filled wrist watch tops. They are cleaned, incinerated and ready to go. My plan is to run them in hot hydrochloric acid first, rinse them thoroughly, then process them in dilute nitric. Just wondering if anyone thinks this is a good way to go, or if this batch should be processed another way.
