What happens if you magnetize fake gold?
Fake gold or gold alloys will be instantly attracted to the magnet. If the metal is attracted to the magnet, then it is either not made of gold or has a meager percentage of it. Gold is a non-ferrous metal, which means it won't attract the magnet. So, even if the item is slightly magnetic, but doesn’t stick to the magnet, then it’s gold-plated.
What happens when you heat up gold?
Take some solid gold and heat it. When it gets hot enough (1064.18 °C or 1947.52 °F), it melts. It was a solid, and now the gold has changed state to become a liquid.
Is it possible to burn gold?
Gold, which is called a noble metal, just sits there molten. That's because it doesn't like to react with anything, and that means it is extremely difficult to "burn" gold. It won't oxidize (combine with oxygen), which is the basis for most "burning" in the conventional sense.

Gold chains and collars commonly have a "clasp" mechanism of some sort, and you may find that only the clasp bit sticks to the magnet. This is because there is a spring inside the clasp mechanism, and gold doesn't make good springs.

Why does a precious metal detector not damage a bar?
The gold sample is assessed in less than a second, and it doesn’t damage the bar or coin. This is due to the absence of chemicals.
