south-seeking pole
Definition
Noun: - The pole of a magnet that, when the magnet is suspended freely and can rotate, aligns itself to point toward the Earth's geographic south. This is the magnetic north pole of the magnet itself, as opposite magnetic poles attract.
Usage
This term is used specifically in the context of magnetism and physics to describe one of the two fundamental poles of a magnet. It is the pole that is attracted to the Earth's geographic south (which is a magnetic north pole).
Examples
- In a simple bar magnet, the south-seeking pole will swing to face south if the magnet is hung from a string.
- When using a compass needle, which is a small magnet, the end marked "S" is its south-seeking pole.
- To identify the south-seeking pole of an unmarked magnet, suspend it freely and see which end points toward the south.
Advanced Usage
- In technical and scientific contexts, the term south-seeking pole is synonymous with the magnetic north pole of the magnet. This is because it seeks the south, but by the convention of naming poles based on their external field, it is the pole of the magnet.
- The concept is crucial for understanding magnetic fields, where like poles repel and opposite poles attract. The Earth's geographic south magnetic region attracts the south-seeking pole of a magnet.
Variants and Related Words
- Magnetic north pole (of a magnet): The technical term for the same pole, based on the direction of the magnetic field lines that emerge from it.
- North-seeking pole: The opposite pole of a magnet, which points toward geographic north.
- Magnetic pole: The general term for either pole of a magnet.
Synonyms
- Magnetic north pole (of the magnet)
Antonyms
- North-seeking pole
- Magnetic south pole (of the magnet)
Noun
-
the pole of a magnet that points toward the south when the magnet is suspended freely
