Does Gold Stick to a Magnet? 3 Tests You Can Try at Home
When it comes to precious metals like gold, there are many myths and misconceptions surrounding their properties. One common question that often arises is whether or not gold sticks to a magnet. In this article, we will explore this question in depth and provide you with three simple tests you can try at home to see for yourself.
The Basics of Gold and Its Properties
Before we delve into the tests, let’s first understand the basics of gold and its properties. Gold is a dense, soft, and malleable metal that is known for its lustrous yellow color. It is one of the most sought-after precious metals in the world and has been used for centuries in jewelry, currency, and various other applications.
Gold is a non-magnetic metal, which means it is not attracted to magnets. Unlike iron, nickel, and cobalt, which are magnetic metals, gold is not influenced by magnetic fields. This unique property of gold makes it an interesting material to study when it comes to magnetism.

Test 1: Magnetic Attraction
The first test you can try at home to determine if gold sticks to a magnet is a simple magnetic attraction test. For this test, you will need a magnet (ideally a strong neodymium magnet) and a piece of gold jewelry or a gold coin.
Steps:
- Hold the magnet close to the gold item.
- Slowly move the magnet around the gold item and observe if there is any magnetic attraction.
- Repeat the process from different angles to ensure accuracy.
If the gold item does not react to the magnet and there is no magnetic attraction, it confirms that gold is not magnetic and does not stick to a magnet.

Test 2: Density Comparison
Another test you can conduct at home to determine if gold sticks to a magnet is a density comparison test. This test compares the density of gold to other metals that are magnetic, such as iron.
Steps:
- Gather a magnet, a piece of gold, and a piece of iron.
- Hold the magnet close to the gold and observe if there is any magnetic attraction.
- Repeat the process with the iron.
- Compare the reactions of the gold and iron to the magnet.
Gold, being a dense metal, will show no magnetic attraction, whereas iron, with its magnetic properties, will be attracted to the magnet. This test demonstrates the difference in density between gold and magnetic metals.

Test 3: Conductivity Test
The third test you can try at home to determine if gold sticks to a magnet is a conductivity test. Gold is an excellent conductor of electricity, while magnetic metals like iron may not conduct electricity as efficiently.
Steps:
- Gather a battery, wires, a small light bulb, a gold item, and an iron item.
- Connect the wires to the battery, light bulb, and the gold item.
- Observe if the light bulb lights up when the wires are connected to the gold.
- Repeat the process with the iron item.
If the light bulb lights up when connected to the gold item but not to the iron item, it confirms that gold is a good conductor of electricity and is not magnetic.
In conclusion, gold does not stick to a magnet due to its non-magnetic properties. By conducting these simple tests at home, you can verify for yourself that gold is a unique and valuable metal with distinct properties that set it apart from magnetic metals.
