No gold is not ferro magnetic. So it will not be picked by a magnet

Pure gold is not magnetic. The less-than-pure 14K gold is often created by taking pure gold (24K) and alloying it with silver and copper to give it the hardness or lustre that the maker wants. But combinations of gold, silver and copper aren't magnetic. Testing gold with a magnet will tell if iron or other ferromagnetic material is alloyed with the gold, but if the magnet does not pick up the gold item being tested, we know nothing more about that gold. Some gold is alloyed with nickel, and nickel is magnetic. As we don't know what item was sold and because we can't know how the 14K gold was made, we can't tell much else from the question. A gold and nickel alloy will respond to a magnet. But what can be told from this? Only that the magnet is reacting to a ferromagnetic material. And that is all.

It will pick up the nails the same way a bar magnet would do!
Try a magnet. A magnet picks up iron. It does not pick up aluminum.
The easiest way to check for steel is to use a magnet. A magnet is going to pick up steel and will not pick up metals that do not contain iron.
A magnet is built in the crane to pick up cars and other vehicles.
with a magnet
it can pick up mild steel metal and that's all i know sorry.
A magnet can pick up tiny iron particles that are in sand.
Depending on how strong the magnet is the amount of paper clips it can pick up will vary. Why don't you test it for yourself?
