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

這次發布的一個關鍵亮點是磁北極的持續移動，它正逐漸靠近俄羅斯。
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.
根據本週發布的世界磁力模型（WMM）更新，地球磁北極有了新的位置。這項旨在追蹤地
球不斷變化的磁場的重要更新將一直有效到 2029 年末。 此版本的關鍵亮點是地磁北極
的持續移動，它正在逐漸靠近俄羅斯——這一趨勢引起了科學家和航海專家的關注。
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.
磁北與真北：有什麼差別？
了解地球地理北極和磁北之間的差異至關重要。地理北極，通常稱為“真北”，是北緯
90° 處的固定點，行星自轉軸與表面相交。相較之下，磁北極遠非靜止，因為它的位置
取決於地球外核內熔融金屬的動態流動。
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.
這些導電的液態金屬在地球自轉和內部熱量的驅動下移動時會產生電流。這種運動產生的
磁場定義了我們星球的兩個極點。然而，與穩定的地理北極不同，磁北極受到地核複雜行
為的影響而逐漸改變。
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.
為什麼新模型很重要？
WMM 是依賴地球磁場的技術的重要工具，包括 GPS 系統和衛星導航。 2025 年更新包括
世界磁模型高分辨率 (WMMHR2025)，它提供了赤道約 300 公里的改進空間分辨率，比標
準模型的 3,300 公里分辨率精確得多。精度的提高確保了從航空到航運等各種行業的可
靠導航。
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.
近幾十年來，磁北極的運動一直在加速，自 1830 年代以來，從加拿大向西伯利亞移動了
約 2,250 公里。 1990年至2005年間，其速度從每年不到15公里激增至每年50至60公里左
右。然而，在過去五年中，科學家觀察到速度突然減至每年 35 公里，這種現象與先前記
錄的任何現象都不同。
“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.
英國地質調查局全球地磁場建模：「WMM 今天正式發布，確保用戶能夠獲得最新信息，以
便他們能夠在未來五年內繼續準確導航。」師 William Brown 博士表示
隨著科學家繼續監測這些變化，像 WMMHR2025 這樣的更新對於理解和適應地球不斷變化
的磁地形仍然至關重要。這些數據不僅支持日常技術，還有助於對地球複雜內部運作的持
續研究。
