Gold has long been treasured for its beauty, rarity, and resistance to corrosion. But when it comes to magnetism, can gold interact with a magnet the same way as iron, nickel, or cobalt? If you’ve ever wondered whether a magnet will stick to gold, you’re in the right place. This article will not only answer that question but also show you how a neodymium magnet can be used to test gold authenticity.
Is Gold Magnetic?
In short, no. Pure gold (24-karat gold) is not magnetic. If you hold a strong neodymium magnet near a gold piece, you won’t feel any attraction. That’s because gold is classified as a diamagnetic metal—it does not attract or stick to a magnet.
Why Doesn’t Gold Stick to a Magnet?
The reason gold doesn’t stick to a magnet lies in its atomic structure. Unlike industrial magnets made from iron-based materials, gold lacks unpaired electrons that create magnetic fields. This means even a powerful neodymium magnet won’t have an effect on it.
How Can a Magnet Help Detect Fake Gold?
While gold itself isn’t magnetic, many counterfeit gold items contain ferromagnetic metals like iron or nickel. If your jewelry or gold coins are attracted to a magnet, they likely contain non-gold metals. However, some counterfeit items use non-magnetic metals like copper, making a magnet test only one piece of the puzzle.
Will a Magnet Stick to Gold Alloys?
Gold is often alloyed with other metals to improve durability. Common gold alloys include:
- 18K gold (75% gold, 25% other metals)
- 14K gold (58.3% gold, 41.7% other metals)
- 10K gold (41.7% gold, 58.3% other metals)
If the alloy contains magnetic metals such as nickel or iron, it may exhibit weak magnetic attraction. However, most jewelry alloys use non-magnetic metals like silver and copper, keeping them non-magnetic.

Frequently Asked Questions
1. Can I use a magnet to verify real gold?
A magnet can help identify fake gold, but it’s not foolproof. Some counterfeit gold contains non-magnetic metals.
2. What type of magnet should I use for gold testing?
For the best results, use a neodymium magnet since it has a strong pull and can easily detect magnetic properties.
3. Do gold-plated items react to magnets?
Gold-plated jewelry may contain a magnetic core underneath the gold layer, causing a weak magnetic reaction.
