One key highlight of this release is the continued movement of the magnetic
north pole, which is edging closer to Russia.

这次发布的一个关键亮点是磁北极的持续移动，它正逐渐靠近俄罗斯。
The Earth’s magnetic north pole has a new position, according to the World
Magnetic Model (WMM) update released this week. This critical update,
designed to track the ever-shifting magnetic fields of our planet, will
remain valid until late 2029. One key highlight of this release is the
continued movement of the magnetic north pole, which is edging closer to
Russia—a trend that has captured the attention of scientists and navigation
experts alike.
根据本周发布的世界磁力模型（WMM）更新，地球磁北极有了新的位置。这项旨在追踪地
球不断变化的磁场的重要更新将一直有效到 2029 年末。 此版本的关键亮点是地磁北极
的持续移动，它正在逐渐靠近俄罗斯——这一趋势引起了科学家和航海专家的关注。
Magnetic North vs. True North: What’s the Difference?
Understanding the difference between Earth’s geographic North Pole and
magnetic north is vital. The geographic North Pole, often called “True North,
” is a fixed point at 90° North latitude where the planet’s axis of
rotation intersects the surface. In contrast, the magnetic north pole is far
from stationary, as its position depends on the dynamic flow of molten metals
within Earth’s outer core.
磁北与真北：有什么差别？
了解地球地理北极和磁北之间的差异至关重要。地理北极，通常称为“真北”，是北纬
90° 处的固定点，行星自转轴与表面相交。相较之下，磁北极远非静止，因为它的位置
取决于地球外核内熔融金属的动态流动。
These conductive, liquid metals create electric currents as they move, driven
by the Earth’s rotation and internal heat. This motion generates the
magnetic field that defines our planet’s two poles. However, unlike the
steady geographic North Pole, the magnetic north pole shifts gradually,
influenced by the complex behavior of Earth’s core.
这些导电的液态金属在地球自转和内部热量的驱动下移动时会产生电流。这种运动产生的
磁场定义了我们星球的两个极点。然而，与稳定的地理北极不同，磁北极受到地核复杂行
为的影响而逐渐改变。
Why Does the New Model Matter?
The WMM is a critical tool for technologies that rely on Earth’s magnetic
field, including GPS systems and satellite-based navigation. The 2025 update
includes the World Magnetic Model High Resolution (WMMHR2025), which provides
improved spatial resolution of approximately 300 kilometers at the equator—
far more precise than the standard model’s 3,300-kilometer resolution. This
increased accuracy ensures reliable navigation for a variety of industries,
from aviation to shipping.
为什么新模型很重要？
WMM 是依赖地球磁场的技术的重要工具，包括 GPS 系统和卫星导航。 2025 年更新包括
世界磁模型高分辨率 (WMMHR2025)，它提供了赤道约 300 公里的改进空间分辨率，比标
准模型的 3,300 公里分辨率精确得多。精度的提高确保了从航空到航运等各种行业的可
靠导航。
The movement of the magnetic north pole has been accelerating in recent
decades, traveling approximately 2,250 kilometers from Canada toward Siberia
since the 1830s. Between 1990 and 2005, its speed surged from less than 15
kilometers per year to around 50 to 60 kilometers annually. However, in the
past five years, scientists observed a sudden deceleration to 35 kilometers
per year—a phenomenon unlike anything previously recorded.
近几十年来，磁北极的运动一直在加速，自 1830 年代以来，从加拿大向西伯利亚移动了
约 2,250 公里。 1990年至2005年间，其速度从每年不到15公里激增至每年50至60公里左
右。然而，在过去五年中，科学家观察到速度突然减至每年 35 公里，这种现象与先前记
录的任何现象都不同。
“The WMM is officially released today, ensuring users can have the most
up-to-date information so they can continue to navigate accurately for the
next five years,” said Dr. William Brown, global geomagnetic field modeler
at the British Geological Survey (BGS).
As scientists continue to monitor these changes, updates like WMMHR2025 will
remain vital for understanding and adapting to Earth’s shifting magnetic
landscape. The data not only supports everyday technologies but also
contributes to ongoing research into the complex inner workings of our planet.
英国地质调查局全球地磁场建模：“WMM 今天正式发布，确保用户能够获得最新信息，以
便他们能够在未来五年内继续准确导航。”师 William Brown 博士表示
随着科学家继续监测这些变化，像 WMMHR2025 这样的更新对于理解和适应地球不断变化
的磁地形仍然至关重要。这些数据不仅支持日常技术，还有助于对地球复杂内部运作的持
续研究。
