Do earth's magnetic field has always run from north pole to south pole?

Yes a magnet has a north pole and a south pole. Magnets generate a magnetic field that "flows" in one direction. To make it easy to understand how two magnets interact, scientists and physicists assign names of "North" and "South" to the opposite ends of the magnet. Some magnets can reverse direction.

If the questioner is referring to north and south magnetic poles, then, yes, a magnetic field is always allocated a direction from north to south (the direction a compass needle would point within that field).
If, on the other hand, the questioner is referring to the locations called Magnetic North and Magnetic South... well, in modern times the magnetic polarity of Magnetic North is a south. But, in the past and, possibly in the future, the magnetic polarities have 'flipped' making the location, Magnetic North, a north pole -but the direction of the magnetic field is always north to south.

∙ 13y agoIt has not always run from the north to the south pole because the earth has been flipped around over the years.

∙ 16y agoyes this phenomenon happens around every 10000 years. it is in the process right now and as a result you may even see aurora in equatorial areas.

∙ 6y agoIt is not exactly north to south; the magnetic poles don't exactly match the geographic poles (which are defined by rotation), and they change over time.

A device that uses the Earths magnetic field to indicate witch way north is?
A compass.
Is the magnetic pole near the Earths true North Pole a magnetic south pole or a magnetic north pole?
Earths geographic North Pole is also currently a magnetic north pole. This is however not always the case because over geological time scales the Earth's magnetic poles flip as a result of changes of flow in Earth's molten core which produces Earth's magnetic field.
How does earths magnetic field change over time?
It changes over time through direction and strength. So therefore Magnetic North becomes Magnetic South.
Where is earth's magnetic field strongest?
where is the earths magnectic field the stongest? the strongest place of the magnectic place is right in the middle of shouth pole and north pole
Why a freely suspended magnet always rest in north and south direction?
A magnet aligns itself along the earth's magnetic field, with its north pole pointing to a location called 'Magnetic North', so called to distinguish it from 'True North'. The magnetic polarity of the location we call 'Magnetic North' is south.
How is the earths magnetic field used for navigation?
Compasses use the magnetic field to navigate always pointing North.
Why do scientists think that earths' magnetic field has not always pointed north?
Every 100,000 years or so, the Earths magnetic field shifts direction. North becomes south, south becomes north.
What causes the poles to be slightly off the true North and South poles?
The Earths magnetic field is always shifting
Can the earths magnetic field move?
Yes it can reverse from North to South
What do scientist not know about earths magnetic field?
When the north pole becomes the south pole.

Is the earths magnetic field constant throghout?
No, the Earth's Magnetic Field acts just like a BAR Magnetic. It has a North and South Pole and its magnetic lines of its force field are more tightly 'compressed' near the Poles than at the Equator. See the image below for an example, or Google "magnetic field lines".
What may cause a compass needle to point to a television rather than earths magnetic north pole?
The television or something in it must be generating a magnetic field.
What is the properties of magnets?
Any magnet will always align itself to north south direction of earths magnetic field. Magnetic needle will always be perpendicular to the direction of current. Stronger magnets attracts weak magnets towards itself if the weak magnet is placed in stronger magnets magnetic field.
What causes the part of earths magnetic field called the magnetosphere to exist?
Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with one pole near the north pole and the other near the geographic south pole. The Inner Van Allen Belt & Outer Van Allen Belt cause the magnetic field.
