Magnetic pole | Earth, Magnetism, Reversal | Britannica
magnetic pole, region at each end of a magnet where the external magnetic field is strongest. A bar magnet suspended in Earth’s magnetic field orients itself in a north–south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole.
What do you mean by Poles of a Magnet? - BYJU'S
The magnetic pole is the region where the external magnetic field is the strongest at each end of a magnet. A pole of a magnet may refer to a magnetic monopole, a hypothetical elementary particle. The magnetic poles of the astronomical bodies are a special case of magnets.
Why do magnets have north and south poles? - Live Science
2023年4月30日 · Scientists have defined a magnet's north pole as the end that would point toward Earth's north pole if the magnet could spin freely.
22.1: Magnets - Physics LibreTexts
There are two types of magnetic poles, called the north magnetic pole and south magnetic pole. North magnetic poles are those that are attracted toward the Earth’s geographic north pole. Like poles repel and unlike poles attract.
How Magnets Work - HowStuffWorks
2022年9月20日 · Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Permanent or hard magnets create their own magnetic field all the time.
21.1: Magnetism and Magnetic Fields - Physics LibreTexts
All magnets have two poles, one called the north pole and one called the south pole. Like poles repel and unlike polls attract (in analogy to positive and negative charges in electrostatics).
Why does Earth have magnetic poles? - Live Science
2023年9月11日 · Earth is the only rocky body in the inner solar system with strong magnetic poles. But where do these poles come from, and what do they do?
22.1 Magnets - College Physics 2e - OpenStax
Experimentation shows that all magnets have two poles. If freely suspended, one pole will point toward the north. The two poles are thus named the north magnetic pole and the south magnetic pole (or more properly, north-seeking and south-seeking …
