If you look at yourgold coins, rings, earrings, necklaces and moregold jewelry,you wonder if they are magnetic. While the simple answer is no, there is more to whether gold is magnetic. Learn more about the magnetism of this precious metal.

Can gold stick to a magnet?
Pure gold by itself cannot stick to a magnet. But if you have a gold alloy, it can stick to a magnet. An example of a gold alloy that can stick to a magnet is gold with more than 20% of the atoms replaced by iron. At very cold temperatures, this gold alloy can magnetize completely by itself.
Will gold of different karats stick to a magnet? Gold jewelry, such as 18 karat gold, 14 karat gold, 10 karat gold and even white gold, can be magnetic depending on the alloys or metals used combined with gold.
If you think your gold coins or jewelry are pure gold, you can test them to see if they are magnetic. If they stick to another metal, chances are your precious metal is not pure gold. Instead, it may contain iron or nickel. Remember that even if it is not magnetic, it may not be pure gold. You can have a piece made of copper, lead or aluminum with a gold coating.
Can you make gold magnetic?
Although pure gold itself is not magnetic, there is a way to make it temporarily magnetic. You do this by placing it in a strong magnetic field. Within this magnetic field, the gold can become somewhat magnetic. Since we do not encounter such strong magnetic fields in our daily lives, we can say with certainty that pure gold is not magnetic.
Why do jewelers add other metals to gold?
Because pure gold is a soft and malleable metal, jewelers often mix other precious metals with it to make the piece more durable, harder and less likely to bend and scratch. They can also mix other metals such as platinum, copper or nickel to give the piece a different color.
Is silver magnetic?
Like gold, silver is not magnetic. You can use a similar process of placing it in a strong magnetic field to make it somewhat magnetic. Knowing that silver is generally not magnetic can help you determine if you have real silver. If it sticks to a magnet, it's a different type of metal.
What types of metals are magnetic?
When these metals are combined with gold, the jewelry (gold jewelry or gold bars/nuggets) can become magnetic. Which metals are attracted to magnets?
Cobalt, iron, nickel, neodymium, samarium and gadolinium are all magnetic metals.
Cobalt is widely used in aircraft engine parts, batteries and dye for ceramics and glass.
Iron is used to make steel for manufacturing and construction.
Nickel is typically used to coat other metals to prevent corrosion. You see it in coins or jewelry. Many manufacturers use it to make alloys such as stainless steel used in home appliances.

One of the most common uses for neodymium is in an alloy with boron and iron to make permanent magnets. A permanent magnet is a magnet that retains its magnetic properties in the absence of a current or inducing field. They are found in cell phones, microphones, electronic instruments and speakers.
Samarium is often combined with cobalt to make incredibly powerful magnets. They are often used in microwave applications because they can remain magnetic at high temperatures. These magnets also made possible devices such as headphones and personal stereos.
Gadolinium is quite useful in various alloys. It is commonly used in electronic components, magnets and data storage drives. The compounds are also used in magnetic resonance imaging (MRI), especially for the detection of cancerous tumors.
What types of metals are not magnetic?
In their pure, natural forms, gold, silver, aluminum, copper, brass and lead are not magnetic. This is because they are all weak metals. Adding iron or steel to these metals can make them stronger and magnetic.
Gold is commonly used in coins, jewelry, electronics, dentistry, aerospace and awards. Silver can also be found in jewelry and coins. It is also used for tableware, mirrors and antibacterial properties.
Aluminum is often used to make cans, kitchen utensils, foils, beer kegs, window frames and even aircraft parts. Copper is of course used for the shilling, but you can also find it in electrical equipment because it is known for its conductivity. Brass is the metal of choice for many musical instruments, but it is also used in alloys for transporting water.

Lead was previously widely used in various materials such as paint, hair dye and pipes. These uses have long been banned since the discovery of its toxicity. Today it is still used in car batteries and for the storage of corrosive liquids.
Why can a metal detector find gold?
Since gold in its pure form is not magnetic, you may wonder how a metal detector finds it. First, not all types of metal detectors can find gold. If your metal detector operates at lower frequencies, it may not find gold due to its low conductivity. However, high-frequency metal detectors can find gold. This is because gold has better conductivity in high frequency waves. Although quite expensive, multi-frequency and PI-type metal detectors are best for finding gold.
How do magnets work?
The science behind magnets is a bit complicated, but simply put, a magnet is an object that attracts iron and other materials. A magnet can generate a magnetic field around itself. Magnets have two poles, the north and south poles. These two poles exert forces on each other. Poles that are similar repel each other, while poles that are different attract each other. When two metals stick together, it means they have different poles.
Now that you know a little more about gold and that it is not magnetic, you can test whether your jewelry or coins are made of pure gold. It may contain magnetic metals. If you have any other questions about gold or other precious metals, please call us or complete our online emailContact Form.
