Is Gold Magnetic?

The straight answer, the physics behind it, and why some real gold jewelry still tugs toward a magnet — plus what the magnet test can and can't prove.

No — pure gold is not magnetic. It's diamagnetic, meaning it's actually repelled by a magnetic field, so faintly that no ordinary magnet can move it. But gold jewelry can still pull toward a magnet through alloy metals or steel clasps, and a non-magnetic result does not prove a piece is real gold.

Applies to solid gold — alloys, clasps, and plated bases can behave differently

Holding a magnet to a gold piece is one of the first things people try — it's quick, it's free, and everyone has a magnet somewhere. The instinct is right, but the conclusion people draw is usually wrong. A magnet can tell you when something definitely isn't solid gold. It can't tell you when something is.

Below is the actual physics of why gold ignores magnets, why some genuine gold jewelry still seems to respond, and exactly how much weight to put on the result.

The Short Answer: Pure Gold Is Not Magnetic

Pure 24K gold is not attracted to magnets — full stop. Hold the strongest magnet you own to a bar of pure gold and nothing happens. This isn't a quirk of purity or finish; it's a basic property of the element.

The reason comes down to electrons. Metals that stick to magnets — iron, nickel, cobalt — are ferromagnetic: they have unpaired electrons whose magnetic moments can line up together and lock onto an external field. Gold's electrons are almost all paired off, so there's nothing for a magnet to grab.

Technically, gold is diamagnetic, which means a magnetic field actually pushes it away rather than pulling it in. When you bring a magnet close, the field nudges gold's paired electrons into orbits that oppose it, creating a tiny repulsion. But "tiny" understates it: gold's magnetic susceptibility is only about −3.4 × 10⁻⁵. Observing that repulsion takes a powerful laboratory magnet and sensitive instruments. With any magnet you'd use at home, real gold does nothing at all — no pull, no push, no reaction.

The one-line version: real gold does not react to a household magnet. If your piece clearly sticks, drags, or clings, that response is coming from something other than gold.

Why Some Gold Jewelry Sticks to a Magnet

If gold isn't magnetic, why do people find real gold pieces that seem to respond to a magnet? Because almost no jewelry is pure gold, and the parts around the gold aren't gold at all.

Alloy metals. Gold is too soft to wear on its own, so jewelry gold is mixed with other metals for strength. Most of those — copper, silver, zinc, palladium — are not magnetic, so standard yellow gold alloys stay non-magnetic. The exception is nickel, which is ferromagnetic and is used in some white gold. Diluted across an alloy, nickel rarely produces a pull you can feel, but a nickel-heavy white gold can show a faint response.

Clasps, springs, and findings. This is the usual culprit. Spring rings and lobster clasps rely on a small steel spring for tension, and steel is strongly magnetic. A solid gold chain can have a clasp that jumps to a magnet while the chain itself is completely inert. Earring posts, butterfly backs, and pin stems are also frequently made of steel or another base metal, even on genuine gold pieces.

Solder points and repairs. Older or repaired jewelry sometimes has non-gold solder or a base-metal core hidden inside a hollow section, which can register on a magnet.

A plated base metal. The most important case: gold-plated jewelry over a steel or nickel base will stick to a magnet. Here the magnet is doing exactly what you want — reaching past the thin gold surface to reveal the core underneath. That's a genuine fail. Learn how plating works in our gold filled vs gold plated guide.

Always test the clasp separately from the body of the piece. A magnetic clasp on a non-magnetic chain usually means the gold is fine and only the finding is steel. If the whole piece drags toward the magnet, that's a different story.

Is 14K Gold Magnetic?

No — solid 14K gold is not magnetic. 14K gold is 58.3% pure gold; the remaining ~42% is alloy metal, usually copper, silver, and zinc. None of those are ferromagnetic, so a genuine 14K piece won't cling to or be dragged by a magnet. The same holds for 10K (41.7% gold) and 18K (75% gold): more alloy or less, the alloy metals in standard yellow and rose gold simply aren't magnetic.

When 14K might show a faint tug: if it's white gold made with nickel, or — far more often — if a steel clasp, spring, or post is what the magnet is actually catching. A slight response localized to the clasp is normal and doesn't mean the gold is fake.

So a strong, unmistakable pull on a piece stamped 14K is a red flag worth following up on. But because so many fakes are non-magnetic too, a 14K piece passing the magnet test doesn't confirm anything on its own. Pair it with the checks in our guide on how to tell if gold is real.

Is White Gold Magnetic?

Usually not — but white gold is the karat gold most likely to show a faint magnetic response. White gold gets its color by alloying gold with white metals. When that alloy uses nickel, you're introducing a ferromagnetic metal into the mix. Spread thinly through the alloy, nickel rarely produces a pull you can actually feel, but a nickel-rich white gold can show a very slight attraction to a strong magnet.

Palladium-based white gold is different. Palladium is not ferromagnetic, so white gold alloyed with palladium instead of nickel shows no magnetic response at all. Many countries have moved toward nickel-free white gold because nickel can cause skin allergies — the European Union restricts how much nickel jewelry can release against the skin.

The takeaway: a barely-there tug on a white gold piece is not proof it's fake — nickel white gold is a legitimate, common alloy. A strong, obvious pull is still a warning sign. And remember that white gold's bright finish comes from rhodium plating over the alloy, which is a separate matter from magnetism; we cover that in does gold tarnish.

How to Do the Magnet Test on Gold

Use a strong magnet. A flat refrigerator magnet is too weak to be useful. A small neodymium (rare earth) magnet is what you want — they're inexpensive at any hardware store and are what makes this test meaningful.

Step by step:

Lay the piece on a flat, non-metallic surface like a wooden table.
Slowly bring the neodymium magnet close to the main body of the item — the chain, band, or pendant, not the clasp.
Watch for any pull. Solid gold shows none: it won't lift, slide, or cling.
Now test the clasp, spring, and any posts or backs separately. These are commonly steel even on real gold, so a response here is expected and not a fail for the gold itself.
Try gently tilting the piece toward the magnet. If it drags or sticks anywhere on the gold body, that section contains a magnetic metal.

Reading the result: a clear pull on the body of the piece means it is not solid gold. No pull means the piece could be gold — or could be one of the many non-magnetic fakes. The magnet has done its job either way; it just can't finish the job alone.

Treat the magnet as the first filter, then move to a hallmark check and at least one conclusive test. Our full walkthrough covers the home and professional tests that actually confirm gold, ranked by how much they prove.

What the Magnet Test Can and Cannot Tell You

The magnet test is a one-way filter. It can eliminate a piece, but it can never confirm one. Here's how to read each outcome:

Result	What It Means	What to Do Next
Strong pull on the body	Not solid gold — contains a ferromagnetic metal like iron, steel, or nickel	Likely plated or fake; a hallmark and acid test can confirm
Only the clasp responds	Normal — clasps and springs are usually steel even on real gold	Retest the body on its own; the gold may be fine
Very faint tug (white gold)	May be nickel in the alloy — not proof of a fake	Inconclusive; confirm with density or professional testing
No response at all	Inconclusive — real gold and most fakes both ignore magnets	Check the hallmark, then acid, density, or XRF testing

The magnet test can rule a piece out but never rule it in. For tests that actually confirm gold, see how to tell if gold is real.

Metals Commonly Confused with Gold

The reason a non-magnetic result proves so little is that the metals most often mistaken for gold are also non-magnetic. Here's how the common look-alikes behave:

Material	Magnetic?	Notes
Gold (pure)	No (diamagnetic)	Very slightly repelled, unmeasurable with a handheld magnet
Brass	No	Copper-zinc alloy; common in cheap "gold" jewelry, passes the magnet test
Copper	No (diamagnetic)	Reddish tone; also non-magnetic, so a magnet won't catch it
Tungsten	Barely (paramagnetic)	Nearly gold's density; used to fake bullion bars, only weakly attracted
Pyrite ("fool's gold")	Barely (paramagnetic)	Iron sulfide, but too weakly magnetic to catch on a household magnet
Steel / iron base	Yes (ferromagnetic)	The one the magnet does catch — common under gold plating

Notice the pattern: brass, copper, tungsten, and pyrite — the classic gold impostors — all behave essentially like gold under a magnet. That's exactly why a "no reaction" result can't confirm gold. Only a steel or iron base gives the magnet something to grab, which is why the test is genuinely useful for catching gold-plated-over-steel fakes and nothing else.

Tungsten deserves a special note: it's paramagnetic (weakly attracted), and its density is almost identical to gold's, which makes it the metal of choice for counterfeit bullion bars. A magnet might reveal a slight pull on a solid tungsten fake, but a thick gold shell can mask even that — which is why serious buyers rely on ultrasound, drilling, or XRF for bars rather than a magnet.

Frequently Asked Questions

Does real gold stick to a magnet?

No. Pure gold is not magnetic and will not stick to a magnet. If a piece clings to a magnet, it contains a ferromagnetic metal like iron, steel, or nickel and is not solid gold. But the reverse isn't proof of anything: most fake gold is made from non-magnetic metals like brass, copper, or tungsten, so a piece that ignores the magnet still needs other tests. See how to tell if gold is real for conclusive checks.

Is 14K gold magnetic?

Solid 14K gold is not magnetic. It's 58.3% gold alloyed with copper, silver, and zinc — none of which are ferromagnetic — so a 14K piece won't cling to a magnet. You may feel a faint tug if the alloy contains nickel or if a steel clasp or spring is nearby, but genuine 14K gold will not stick to or be pulled across a surface by a magnet.

Is 18K gold magnetic?

No. At 75% gold, 18K has even less alloy metal than 14K, and its usual alloy metals (copper, silver, palladium, zinc) are not ferromagnetic. Solid 18K gold shows no magnetic attraction. Any pull you notice almost always comes from a steel clasp, spring, or pin rather than the gold itself.

Is white gold magnetic?

Usually not, but it's the karat gold most likely to show a faint response. Some white gold is alloyed with nickel, which is ferromagnetic. Diluted in the alloy, nickel rarely produces a pull you can feel, but a strong nickel-white-gold piece can show a very slight attraction. Palladium-based white gold shows none. A slight tug alone doesn't mean it's fake — nickel is a legitimate white-gold alloy in many countries.

Is gold-plated jewelry magnetic?

It depends entirely on the base metal under the plating. Gold-plated over brass or copper is not magnetic. Gold-plated over steel or a nickel-heavy base will stick to a magnet — a clear sign the piece is plated, not solid gold. Because the thin gold surface hides what's underneath, the magnet is one of the few home tests that can reach past the plating to the core.

Why is my gold necklace slightly attracted to a magnet?

The most common reason is the clasp. Spring rings, lobster clasps, and the tiny springs inside them are usually made of steel, which is strongly magnetic even when the chain itself is solid gold. Test the chain and the clasp separately. If only the clasp responds, the gold is likely fine. If the whole chain drags toward the magnet, the chain is not solid gold.

What metals are magnetic?

Only a few metals are ferromagnetic — strongly attracted to ordinary magnets. The main ones are iron, nickel, cobalt, and most steels (which are iron-based). Many other metals are technically paramagnetic (very weakly attracted, like tungsten) or diamagnetic (very weakly repelled, like gold, copper, silver, and lead), but those effects are far too weak to notice with a handheld magnet.

Can fake gold be non-magnetic?

Yes — and this is why the magnet test can't confirm gold. Most counterfeit and imitation gold is made from non-magnetic metals: brass, bronze, copper, and gold-plated tungsten all ignore a magnet just like real gold does. A piece that fails to stick has only cleared one low bar. To actually confirm gold, you need a hallmark check plus acid, density, or professional XRF testing.

Is a magnet enough to test if gold is real?

No. A magnet is a useful first filter — a strong pull rules a piece out as solid gold — but it can never rule gold in, because so many fakes are non-magnetic. Think of it as one quick screen among several. Once you know the karat and weight, a genuine piece is worth roughly $77.30 per gram for 14K at the posted spot price (updated Jul 11, 2026, 9:25 PM UTC); you can check yours with our gold calculator. For a full set of reliable tests, see how to tell if gold is real.

Does gold ever get repelled by a magnet?

In principle, yes — gold is diamagnetic, so a magnetic field pushes it away very slightly. But the effect is minuscule (gold's magnetic susceptibility is about −3.4 × 10⁻⁵) and needs an extremely strong field and sensitive equipment to observe. With any magnet you'd use at home, real gold simply shows no reaction at all.
