But researchers at Tohoku University recently discovered that gold can in fact be magnetized by applying heat.
Is pure gold ferromagnetic?
Although pure gold is not magnetic all on its own , there is a way to make it temporarily magnet. You can do this by placing it in a strong magnetic field. Within this magnetic field, the gold can become slightly magnetic.
Is Silver ferromagnetic?
“ Silver is not noticeably magnetic , and exhibits only weak magnetic effects unlike iron, nickel, cobalt, and the like,” says Martin. “If your magnet sticks strongly to the piece, it has a ferromagnetic core and is not silver.” Fake silver or silver-plated items are generally made of other metals.
Will a magnet stick to real gold?

What happen if a magnet is cut in half?
You can think of a magnet as a bundle of tiny magnets, called magnetic domains
Does gold float in water?
Gold is hydrophobic : it repels water. Because of this, even if the piece of gold is first completely submerged, if it gets near the surface it will throw off the water above it and float. ... Since most placer gold is flat and thin, its weight is small relative to its circumference so it will usually float.
