Why do magnets have north and south poles? - Live Science
2023年4月30日 — Earth has its own magnetic field, too — it's what makes a compass needle work. Scientists have defined a magnet's north pole as the end that would point toward Earth's north pole if the...
How to Determine North And South Pole of Magnet? - Stanford Magnets
2024年9月3日 — It is not easy to determine the two poles of a magnet since they look the same if unmarked. Here are a few tips for you to identify the poles of magnets. 1. The Polarity of the Earth. The Earth is a giant magnet, and we can identify its geomagnetic poles using its geographic poles.

Magnetism is a subject that includes the properties of magnets, the effect of the magnetic force on moving charges and currents, and the creation of magnetic fields by currents. There are two types of magnetic poles, called the north magnetic pole and south magnetic pole.

2024年2月22日 — The magnet’s two poles are labeled N and S for north-seeking and south-seeking poles, respectively. MISCONCEPTION ALERT: EARTH'S GEOGRAPHIC NORTH POLE HIDES AN S. The Earth acts like a very large bar magnet with its south-seeking pole near the geographic North Pole.
Magnetic north and south pole’s behavior is not unlike electric charges. For magnets, like poles repel and opposite poles attract. A permanent magnet will attract a metal like iron with either the north or south pole.

Figure 22.4 One end of a bar magnet is suspended from a thread that points toward north. The magnet’s two poles are labeled N and S for north-seeking and south-seeking poles, respectively. Earth acts like a very large bar magnet with its south …
compass needle’s tip is (by definition) “N”, so the compass points towards (is attracted to) the “S” pole of other magnets. The Earth is a giant magnet: A compass points towards the geographic “North” of the planet, so the magnetic “S” pole (of the giant hidden magnet) sits up near the planet’s geographic N pole!

One end of a bar magnet is suspended from a thread that points toward north. The magnet’s two poles are labeled N and S for north-seeking and south-seeking poles, respectively. The Earth acts like a very large bar magnet with its south-seeking pole near the geographic North Pole.
Magnetism - Summary – The Physics Hypertextbook
Regions on a magnet where the forces are the strongest. Come in two types — north pole and south pole. often shortened to north and south; or abbreviated N and S; Magnetic poles always occur in north-south pairs called dipoles. Combinations of of dipoles are called multipoles. Some multipole arrangements have special names
