A magnet is used to check whether an object is gold or silver or simply plated. Everyone knows (or should) that neither gold nor silver is magnetic. Or is that the case?

Turns out both gold and silver exhibit magnetic properties ... just not the attractive kind. Both minerals repel both north and south magnetic poles.

Who knew?

The force of repulsion is so small compared to the mass of metal it will frequently go unnoticed.

Since both of these minerals are sold as colloidal suspensions used for anti-bacterial properties ... wonder if the diamagnetic property is what also kills bacteria?

Anything to back this up? I took a couple of silver coins to see if they would affect my, very accurate, compass. No effect at all. Compass needle never moved.
