Understanding Earth's N/S Poles: Magnetic, Geographic, Geomagnetic, & Dip

Click For Summary
SUMMARY

The discussion clarifies the distinctions between Earth's magnetic north/south poles, geographic north/south poles, geomagnetic north/south poles, and dip north/south poles. The Earth's magnetic north pole is technically a magnetic south pole, as it attracts the north pole of a magnet. This terminology can lead to confusion, as the magnetic north pole is located in the northern hemisphere, yet is defined as a south pole due to its magnetic properties. Understanding these definitions is crucial for accurate navigation and comprehension of Earth's magnetic field.

PREREQUISITES
  • Basic understanding of magnetism and magnetic poles
  • Familiarity with geographic coordinate systems
  • Knowledge of Earth's magnetic field and its properties
  • Concept of geomagnetism and its implications
NEXT STEPS
  • Research the differences between geographic and geomagnetic coordinates
  • Explore the concept of magnetic declination and its effects on navigation
  • Learn about the Earth's magnetic field reversals and their historical significance
  • Study the tools used for measuring magnetic fields, such as magnetometers
USEFUL FOR

Students of physics, geographers, navigators, and anyone interested in understanding the complexities of Earth's magnetic and geographic poles.

In reading my physics book, there was mention of different types of poles. I was hoping someone could explain the differences and possibly supply a visual representation of the poles with respect to each other as to where they lie on Earth. The different poles were the magnetic N/S, geographic N/S, geomagnetic N/S, and dip N/S.

Also, going simpler, is Earth's geographic north, located near the magnetic north or south pole? I've seen both, like, mention of Earth's north pole, actually being a south pole, yet we still call it magnetic north. I don't quite understand that, at least why we call it magnetic north when its actually a south pole.

We call the Earth's magnetic north pole a "north" pole because it is located in the north. We call a magnet's north pole a "north" pole because, if allowed to rotate freely in a horizontal plane, it will point northward.

Opposite poles attract. So the Earth's "north" pole is a magnetic south pole.

That just seems like it leads to unnecessary confusion. I feel it'd make more sense just to call our north magnetic pole a south magnetic pole since that's what by definition it is. Thanks for an explanation though.
