Looking for a magnet that can attract gold

2011-11-22  - Yes it can be attracted by a very very large rare earth magnet (so even can quartz -- not practical nor affordable). - Gold has a specific atomic resonance frequency (I think it was something like 1-7Hz or less); it should play a role fine tuning the exciter/inductor (John Hutchison is a friend of mine).

Q A: Is gold magnetic? Department of Physics ...

2007-10-22  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 magnetize on their own, at ...
