The Geomagnetic poles (dipole poles) are the intersections of the Earth's surface and the axis of a bar magnet hypothetically placed at the center the Earth by which we approximate the geomagnetic field. There is such a pole in each hemisphere, and the poles are called as "the geomagnetic north pole" and "the geomagnetic south pole", respectively. On the other hand, the magnetic poles are the points at which magnetic needles become vertical. There also are "the magnetic north pole" and "the magnetic south pole". The geomagnetic or magnetic south (north) poles correspond to the N (S) -pole of a magnet.

What is the relationship between the geographic and geomagnetic poles?
The geographic poles are the points where the Earth's axis of rotation intersects its surface, while the geomagnetic poles are where the Earth's magnetic field lines are perpendicular to the surface. The geographic poles are fixed, while the geomagnetic poles move due to changes in the Earth's magnetic field.
What are the three magnetic poles?
The three magnetic poles are the north magnetic pole, the south magnetic pole, and the geomagnetic pole. The north and south magnetic poles are where the Earth's magnetic field lines converge and point vertically into or out of the Earth's surface, while the geomagnetic pole is the point on the Earth's surface above the axis of the magnetic field.
What is the process by which Earth's magnetic poles change places?
The process by which Earth's magnetic poles change places is known as geomagnetic reversal. This occurs when the Earth's magnetic field weakens, causing the north and south magnetic poles to switch positions. This reversal can take thousands of years to complete.
What happens to earths magnetic poles over time?
Earth's magnetic poles are not fixed; they undergo gradual shifts and periodic reversals over geological timescales. The magnetic field can drift, causing the poles to move, sometimes by several kilometers per year. Additionally, every few hundred thousand years, the magnetic poles can completely reverse, a phenomenon known as geomagnetic reversal. These changes are driven by the dynamics of the Earth's molten outer core, where the magnetic field is generated.
The angle of difference between the geographic and magnetic poles is called the declination How does the declination change as you move north from where you live?
The angle between the geographic and magnetic poles extends more towards the east, as you move to the north. The magnetic pole is actually near Greenland.

What determines the force between like magnetic poles?
The force between like magnetic poles is determined by the strength of the magnetic poles and the distance between them. The force decreases as the distance between the poles increases.
What is it called when the earths poles switch positions over time?
The phenomenon you're referring to is known as geomagnetic reversal or magnetic pole reversal. This occurs when the Earth's magnetic field flips its polarity, causing the magnetic north and south poles to switch positions.
The angle of difference between the geographic and magnetic poles is called the declination How does the declination change as you move north from where you live?
The angle between the geographic and magnetic poles extends more towards the east, as you move to the north. The magnetic pole is actually near Greenland.
What statement is true about Earth's poles?
Only the magnetic poles wanderD.Earth's magnetic and geographic poles are generally not in the same place.Geographic poles are defined by Earth's rotation.
Is earth magnetic poles moving?
Yes Called geomagnetic reversal it happens once every few hundred thousand years and the next is due soon, apparently.
What is the term for the attraction or repulsion between the poles of magnetic?
magnetic force
Force of pushing or pulling between magnetic poles?
The force of pushing or pulling between magnetic poles is known as the magnetic force. This force is caused by the interaction of the magnetic fields of the two poles and acts in a direction determined by the orientation of the poles (attraction between opposite poles and repulsion between like poles). The strength of the force depends on the distance between the poles and the strength of the magnets.
What happens to the magnetic orientation of rocks as the poles reverse?
During a magnetic pole reversal, the magnetic orientation of rocks changes to align with the new orientation of the Earth's magnetic field. This means that the magnetization of rocks will also reverse during a geomagnetic field reversal event.
What causes geomagnetic reversals?
Geomagnetic reversals are believed to be caused by changes in the flow of molten iron within the Earth's outer core. As the flow patterns change, it can lead to the weakening and shifting of the Earth's magnetic field, eventually resulting in a reversal of the magnetic poles. The exact mechanism behind these changes is still not fully understood by scientists.
