magnetic pole
C1Scientific/Technical
Definition
Meaning
One of the two points on a magnet or the Earth's surface where the lines of magnetic force are vertical and converge; the north-seeking or south-seeking point of a magnet.
It also refers to either of the two locations on the Earth's surface where the planet's magnetic field points vertically downwards (south magnetic pole) or upwards (north magnetic pole), distinct from the geographic poles.
Linguistics
Semantic Notes
The term is polysemous, referring to both the points on a physical magnet and the specific, shifting locations on Earth related to its magnetic field. Context usually clarifies which meaning is intended.

Context Usage
Business
Rare, except in industries related to navigation, geology, or hardware manufacturing.
Academic
Standard term in physics, earth sciences, geology, and geography. Used in textbooks and research on geomagnetism.
Everyday
Used in general explanations about compasses, the Earth, or magnets. Not common in casual conversation.
Technical
Precise term in engineering (electrical, materials), geology, navigation, and physics.
Examples
By Part of Speech
adjective
British English
- The magnetic-pole reversal data was crucial.
- We studied the magnetic-pole shift.
American English
- The magnetic-pole reversal data was crucial.
- We studied the magnetic-pole shift.
Examples
By CEFR Level
- A compass needle points to the north magnetic pole.
- The north magnetic pole is not in the same place as the geographic North Pole.
- Scientists track the gradual movement of the Earth's magnetic poles over time.
- The impending reversal of the magnetic poles, a complex geomagnetic process, has been a subject of intense scientific study and public speculation.
Learning
Memory Aids
Mnemonic
Think of a bar magnet: its ends are its POLES, and they're MAGNETIC. For Earth, imagine a giant bar magnet inside, tilted and with its poles not quite at the top and bottom.
Conceptual Metaphor
The Earth/planet as a giant magnet (with poles).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'полюс' alone, which can also mean 'geographic pole'. Always specify 'магнитный полюс' for clarity.
- The Russian 'полюс' is a direct cognate, but the English term is a fixed noun phrase.
Common Mistakes
- Confusing 'magnetic pole' with 'geographic pole'.
- Using 'pole' alone when the magnetic context isn't clear.
- Saying 'magnet pole' instead of the standard 'magnetic pole'.

FAQ
Frequently Asked Questions
No, they are not. The geographic poles are fixed points where the Earth's axis of rotation meets its surface. The magnetic poles are locations where the planet's magnetic field is vertical, and they slowly wander over time.
Yes, geological evidence shows that the Earth's magnetic field has reversed polarity many times in the past, meaning the north magnetic pole becomes the south magnetic pole and vice versa. This process takes thousands of years.
A compass needle is a small magnet. Its north-seeking end is attracted to the Earth's magnetic south pole (which is near the geographic North Pole), aligning it with the planet's magnetic field lines.
No, it is a general term in physics. Any magnet, from a small fridge magnet to a star, has a north and south magnetic pole.
