Is True North Changing?

Last updated on 8 min read

Yes, true north is changing due to shifts in Earth’s magnetic field, with the magnetic north pole moving rapidly toward Siberia at 30–40 miles per year as of 2026.

Why is true North moving?

True north isn’t moving—the magnetic north pole is shifting because Earth’s molten outer core creates a dynamic magnetic field.

Imagine a giant, slow-motion blender filled with liquid metal churning beneath our feet. That’s Earth’s outer core, and its swirling iron and nickel generate electric currents. Those currents power our planet’s magnetic field, which never stays perfectly still. Right now, the magnetic north pole is sprinting from Canada toward Siberia at speeds that would make Olympic sprinters jealous. The World Magnetic Model updates every five years to keep navigation systems from going haywire—because, honestly, this is the best way to track such a fast-moving target.

Does magnetic north change over time?

Absolutely—magnetic north isn’t a fixed point; it’s constantly on the move thanks to the restless churn of Earth’s outer core.

Picture true north as the unmoving center of a spinning top. Magnetic north? That’s more like the wobbling tip of the top, always shifting. This drift creates something called “magnetic declination”—the gap between where your compass points and true north. For anyone relying on a compass—hikers, pilots, or even smartphone apps—the declination changes over time. That’s why you need updated maps or tools like NOAA’s Magnetic Field Calculator to stay on course. Skip this step, and you might end up walking in circles.

Where is the true North Pole now?

The true North Pole hasn’t budged—it’s still locked at 90°N in the Arctic Ocean, floating under shifting sea ice.

Here’s the thing: the geographic North Pole isn’t on solid ground. It’s smack in the middle of the Arctic Ocean, where the ice is often just a few meters thick. GPS devices love this spot because it’s fixed and reliable. Meanwhile, compasses are chasing the magnetic north pole, which was hanging out near 86.4°N, 163.4°E back in 2020. The difference between the two poles is why your phone’s GPS and your compass might not always agree.

How often does true North Change?

True north never changes—it’s the magnetic north pole that’s always drifting, sometimes as fast as 60 km (37 miles) per year.

Back in the 1990s, magnetic north was ambling along at about 10–15 km per year. Now? It’s hauling tail toward Siberia at nearly four times that speed. While true north stays put, the magnetic pole’s sprint means declination values for every location on Earth need fresh updates. That’s why the World Magnetic Model typically refreshes every five years. Miss an update, and your navigation could be off by miles.

Is the North Star always true north?

Not forever—today Polaris is within 0.7° of true north, but Earth’s wobble means it won’t stay this way.

Earth spins like a slightly unbalanced top, tracing a 26,000-year wobble called axial precession. That wobble makes the North Celestial Pole circle the sky slowly. Around 2500 BCE, Thuban held the title of North Star. By 14,000 CE, Vega will take over. For now, Polaris is close enough to true north for most practical uses—like camping or stargazing. But if you’re doing precision work, like aligning a telescope, you’ll want to double-check its position.

How far off is Polaris from true north?

Polaris sits about 0.7° away from true north—roughly the width of your little finger held at arm’s length.

That tiny gap is usually negligible for casual navigation. Point your finger at Polaris, and you’re basically facing true north. But if you’re navigating by the stars or setting up a telescope, that 0.7° difference can add up. For exact alignment, grab a star chart or an astronomy app to see how close Polaris is to the celestial pole this year.

Should I use true north or magnetic north?

Use true north for GPS navigation; use magnetic north for compass work when GPS isn’t an option.

GPS devices lock onto satellites to pinpoint your location, so they rely on true north. But when you’re out in the wild with just a compass, you’ll need to adjust for magnetic declination—the gap between magnetic north and true north at your spot on the map. In New York, for example, magnetic north is about 13° west of true north as of 2026. Add that 13° to your compass reading, and you’ll be pointing in the right direction.

How many miles has magnetic north moved?

Since the 1990s, magnetic north has traveled over 1,000 miles (1,600 km), racing from Canada to Siberia at 30–40 miles (50–65 km) per year.

This isn’t a slow drift—it’s a full-blown sprint. From 1831 to 1990, the pole moved about 1,000 km total. Now, it covers that distance in just a few decades. The World Magnetic Model has to update more often—sometimes annually—to keep up. This shift affects everything from smartphone compasses to runway labels at airports, which must be repainted to match the new magnetic north.

Is the North Star true north or magnetic north?

Polaris, the North Star, points to true north, not magnetic north.

Here’s the key difference: Polaris sits almost directly above Earth’s rotational axis, so it aligns with the geographic North Pole. Magnetic north, on the other hand, is where your compass needle points due to Earth’s magnetic field. Depending on where you stand, magnetic north can be dozens of degrees away from true north. So if you face Polaris, you’re facing true north—no compass adjustment needed.

How many degrees off is magnetic north from true north?

Magnetic declination varies wildly by location; in 2026 it ranges from about 30° west in parts of Africa to 26° east near New Zealand.

In the continental U.S., the gap is smaller but still important. On the West Coast, declination is nearly zero, but in Maine, it’s over 15° east. Pilots, hikers, and surveyors can’t ignore this difference—it can throw off your route by miles over long distances. The NOAA Magnetic Field Calculator is your best friend for finding the exact declination in your area.

How do you convert True North to magnetic north?

To turn a magnetic bearing into true north, add the local declination; to go from true to magnetic, subtract it.

Let’s say your compass reads 100°, and your location has a 10° east declination. Your true bearing is 110°. The math is simple: True Bearing = Magnetic Bearing + Declination (if east) or True Bearing = Magnetic Bearing – Declination (if west). Most GPS units handle this automatically, but knowing the formula helps when you’re off-grid and your phone dies.

Why does a compass always point north?

A compass needle points north because it aligns with Earth’s magnetic field, which runs from the southern magnetic hemisphere to the northern magnetic hemisphere.

This might sound backwards, but remember: the “north” end of a compass needle is actually a magnetic south pole. It’s pulled toward Earth’s magnetic south pole, which lurks near the geographic North Pole. That’s why the needle’s north end points north. Flip it around in the Southern Hemisphere, and the south end of the needle gets pulled toward Earth’s magnetic north pole near the geographic South Pole.

Where is the strongest attraction force of the magnet?

The magnetic field is strongest at the poles of a magnet, with the maximum pull right at the very tip of each pole.

Ever struggled to separate two magnets stuck end-to-end? That’s the power of the poles. In a bar magnet, the field lines bunch up tightest at the ends, then spread out toward the middle where the field weakens. Earth follows the same rule—the magnetic poles have the strongest pull, while the field fades near the equator. That’s why compass needles swing so decisively toward the poles.

Why is the North Pole called the North Pole?

It’s named for its position at the northern end of Earth’s rotational axis, distinguishing it from the Magnetic North Pole.

The term “pole” just means the extreme end of something—in this case, the northernmost point on Earth’s axis. Ancient explorers named it based on its geography, not its magnetism. Unlike the South Pole, which sits on solid ground in Antarctica, the North Pole floats in the Arctic Ocean, covered by ice that’s only a few meters thick. It’s a moving target, but the name has stuck for centuries.

Why does the earth’s magnetic field go from south to north?

Earth’s magnetic field flows from the southern magnetic hemisphere to the northern magnetic hemisphere due to the movement of molten iron in the outer core.

Picture a giant loop of electric current inside Earth, generated by swirling liquid iron in the outer core. This current creates a dipole field, like a bar magnet tilted about 11° from Earth’s rotational axis. The field lines pop out near the geographic South Pole (but it’s a magnetic north pole) and dive back in near the geographic North Pole (a magnetic south pole). That’s why a compass’s north end points toward the magnetic north pole in the Arctic. Over millions of years, this field can even flip, swapping north and south—a mind-bending process that’s happened many times in Earth’s history.
