⚡ Short Answer: Pure tungsten is not magnetic in any practical sense. It is weakly paramagnetic — meaning it shows a tiny, temporary attraction to a magnetic field that vanishes the moment the field is removed. You will never see a magnet stick to a tungsten block.
Tungsten. The name alone sounds like it belongs in a Marvel script. It is the metal used in light bulb filaments, military armour-piercing rounds, and your favourite ring — and yet most people have no idea whether it is magnetic or not.
That question turns out to be genuinely interesting. The answer is yes and no — and the reason why tells you a lot about how magnetism actually works at the atomic level. Let's dig in.
Magnetic type: Paramagnetic (not ferromagnetic)
Attracted to magnets? Barely — effect is undetectable in everyday use
Retains magnetism? No — magnetism disappears the moment the external field is removed
Tungsten carbide rings magnetic? Sometimes — depends on the binder metal used (cobalt vs nickel)
1. What Is Tungsten, Exactly?
Before we get into the magnetic stuff, a quick fact-dump on tungsten itself — because this metal deserves more respect than it gets at dinner parties.

The name "tungsten" comes from the Swedish words tung sten, meaning "heavy stone." Its symbol W comes from Wolfram, its older Germanic name. Medieval German smelters noticed it wrecked tin smelting — they said it "devoured tin like a wolf." Honestly, a respectable origin story.

2. The Three Types of Magnetism (Made Simple)
To understand where tungsten sits, you need to understand the three main magnetic categories. Don't worry — no physics degree required.
| Type | What It Means | Examples | Retains Magnetism? |
|---|---|---|---|
| Ferromagnetic | Strongly attracted to magnets. Magnetic domains align permanently. | Iron, Nickel, Cobalt | ✅ Yes |
| Paramagnetic | Weakly attracted. Unpaired electrons align temporarily with a field. | Tungsten, Aluminium | ❌ No |
| Diamagnetic | Slightly repelled by magnetic fields. | Copper, Silver, Gold | ❌ No |
Source: Neo Magnets · DEK Manufacturing
Tungsten sits in the paramagnetic column. It is not in the exciting "stick-to-the-fridge" category (ferromagnetic), nor in the "actively runs away from magnets" camp (diamagnetic). It is the Switzerland of magnetic behaviour — technically picking a side, but barely.
3. Why Is Tungsten Paramagnetic? The Atomic Reason
This is where it gets genuinely fascinating — and surprisingly logical once you see it.
- Electron configuration matters: Magnetism arises from electrons. Specifically, it comes from unpaired electrons spinning in their orbitals.
- Tungsten has unpaired electrons: Its 5d orbital contains a small number of unpaired electrons. These create tiny magnetic moments.
- But the effect is tiny: Most electrons in tungsten are paired, which means their magnetic moments cancel each other out almost entirely.
- Result — weak, temporary alignment: Under an external field, tungsten's unpaired electrons weakly align with the field. Remove the field, and those electrons snap back to their random orientations. Magnetism gone.
- No permanent magnetism: Tungsten has no magnetic domains (organised regions of aligned atoms) like iron does. Without domains, permanent magnetisation is impossible.

At room temperature, tungsten's magnetic susceptibility (χ) is approximately +6.8 × 10⁻⁶ emu/g. For comparison, iron's susceptibility is in the range of 10³ emu/g — several thousand times stronger. In practical terms, tungsten's paramagnetism is essentially undetectable without laboratory instruments. (Source: VMT CNC)
4. Key Factors That Affect Tungsten's Magnetic Behaviour
It is not completely fixed. Tungsten's magnetic response does shift depending on a few conditions:
- Temperature: According to Curie's Law, higher temperatures reduce magnetic susceptibility. As temperature rises, thermal energy disrupts electron alignment. So tungsten is slightly more magnetic when cold — still not enough to feel it, but measurable in a lab.
- Applied magnetic field strength: A stronger external field forces more of tungsten's unpaired electrons to align temporarily. Once removed, the effect disappears completely.
- Purity of the metal: Pure tungsten behaves predictably. The moment you introduce impurities — especially ferromagnetic ones like iron or cobalt — magnetic behaviour can change noticeably.
- Alloying elements: Tungsten alloys (especially tungsten carbide) often include binder metals. Those binders change everything. More on that below.

5. Are Tungsten Carbide Rings Magnetic?
This is the question that most people actually care about — especially anyone who owns or is buying a tungsten ring.
Here is the thing: almost no tungsten ring is made from pure tungsten. They are made from tungsten carbide, a compound that requires a binder metal to hold it together during manufacturing.
| Ring Type | Binder Metal | Magnetic? | Notes |
|---|---|---|---|
| Pure Tungsten Ring | None | ❌ No (barely paramagnetic) | Rare in commercial rings |
| Tungsten Carbide (Nickel Binder) | Nickel | ❌ No | Most hypoallergenic option |
| Tungsten Carbide (Cobalt Binder) | Cobalt | ⚠️ Weak — yes | Cobalt is slightly ferromagnetic |
| Tungsten Carbide (Iron-contaminated) | Iron impurities | ⚠️ More noticeable | Lower quality alloys |

- Cobalt-bound tungsten carbide can show a weak magnetic pull. Cobalt has its own ferromagnetic tendencies, and those bleed into the alloy's overall behaviour.
- Nickel-bound tungsten carbide rings are the standard for jewellery. They are essentially non-magnetic in any practical sense.
- A quick magnet test at home: hold a neodymium magnet (from an old hard drive) near the ring. If it pulls, the binder is likely cobalt. If nothing happens, it is probably nickel-bound.

6. Tungsten's Magnetic Susceptibility: By the Numbers
If you like hard data — here it is, properly sourced.
| Metal | Magnetic Type | Magnetic Susceptibility (χ) |
|---|---|---|
| Iron (Fe) | Ferromagnetic | ~200,000 × 10⁻⁶ cm³/mol |
| Nickel (Ni) | Ferromagnetic | ~600 × 10⁻⁶ cm³/mol |
| Aluminium (Al) | Paramagnetic | +16.5 × 10⁻⁶ cm³/mol |
| Tungsten (W) | Paramagnetic | +1.3–1.8 × 10⁻⁵ cm³/mol |
| Copper (Cu) | Diamagnetic | −5.46 × 10⁻⁶ cm³/mol |
| Gold (Au) | Diamagnetic | −28 × 10⁻⁶ cm³/mol |
Source: Neo Magnets · VMT CNC
The positive susceptibility value confirms tungsten is paramagnetic. The small magnitude confirms it is barely so. Iron's susceptibility dwarfs tungsten's by orders of magnitude — that is why iron sticks to magnets and tungsten does not.
7. Why Tungsten's Low Magnetism Is Actually an Advantage
You might think "not very magnetic" sounds like a weakness. In many industries, it is precisely what makes tungsten the best tool for the job.
- Medical equipment (MRI machines): MRI environments are magnetically aggressive. Non-magnetic or low-magnetic materials are essential for nearby components. Tungsten's minimal magnetic response makes it suitable for shielding and weighting within medical tools.
- Precision electronics: Magnetic interference in circuit boards and sensors can corrupt readings. Tungsten's weak paramagnetism ensures it does not affect sensitive instruments.
- Aerospace and defence: Kinetic energy penetrators (armour-piercing rounds) use tungsten alloys partly because of their density and partly because their low magnetism does not interfere with guidance systems.
- Radiation shielding: Tungsten's high density (19.25 g/cm³) and magnetic neutrality make it ideal for X-ray and gamma-ray shielding in medical and nuclear settings.
- Jewellery: Tungsten rings look like steel but do not interfere with phone compasses, cardiac monitors, or electronic access systems. That is a genuinely useful property for wearers.

8. How Do Scientists Actually Measure Tungsten's Magnetism?
You cannot feel tungsten's paramagnetism with your hands. So how do scientists confirm it exists at all? Two primary methods:
- Gouy Balance Method: A tungsten sample is placed in a glass tube and suspended in a magnetic field. The weight of the sample changes ever so slightly when the magnet is switched on. A precision scale detects the change. This shift is used to calculate magnetic susceptibility.
- SQUID Magnetometers (Superconducting Quantum Interference Device): These lab instruments detect extraordinarily small changes in magnetic flux. They are so sensitive they can measure the paramagnetism of tungsten even at very low temperatures with high precision.
Neither of these is something you can replicate in your kitchen, which is why tungsten's paramagnetism is a laboratory fact rather than a household observation.

9. Tungsten vs Other Metals: A Full Comparison
To put tungsten's magnetic (and physical) properties in context, here is how it stacks up:
| Metal | Density (g/cm³) | Melting Point (°C) | Magnetic Type | Common Use |
|---|---|---|---|---|
| Tungsten (W) | 19.25 | 3,422 | Paramagnetic | Filaments, armour, rings |
| Gold (Au) | 19.32 | 1,064 | Diamagnetic | Jewellery, electronics |
| Iron (Fe) | 7.87 | 1,538 | Ferromagnetic | Construction, magnets |
| Cobalt (Co) | 8.90 | 1,495 | Ferromagnetic | Alloys, batteries |
| Aluminium (Al) | 2.70 | 660 | Paramagnetic | Packaging, aerospace |
| Copper (Cu) | 8.96 | 1,085 | Diamagnetic | Wiring, plumbing |
Sources: Encyclopaedia Britannica · Royal Society of Chemistry
One interesting note: gold and tungsten have nearly identical densities. This is why counterfeiters have historically drilled holes in gold bars and filled them with tungsten rods — a scam that has been documented since the 1980s, according to Wikipedia. Tungsten's low magnetism makes detection even harder without proper testing equipment.

10. Common Myths About Tungsten and Magnetism
The internet has some confident (and wrong) answers to this question. Let us clear them up:
-
Myth: "Tungsten is completely non-magnetic."
Reality: Technically incorrect. It is paramagnetic — just so weakly so that it functions as non-magnetic in virtually every practical context. -
Myth: "All tungsten carbide rings are non-magnetic."
Reality: Rings with cobalt binders can show measurable magnetic attraction. Always check the binder type if magnetism matters to you. -
Myth: "Tungsten can be magnetised like iron."
Reality: No. Tungsten has no magnetic domains. It cannot hold a permanent magnetic charge under any standard conditions. -
Myth: "Higher purity = non-magnetic."
Reality: Higher purity actually reveals tungsten's true paramagnetic nature more clearly. Impurities (especially ferromagnetic ones) can increase magnetism in low-grade samples.
