True or False The Earth's North Magnetic Pole is in the same place as the North Pole?
False. The Earth's magnetic fields are constantly shifting, and have been at widely different points over the Earth's history. The North Pole (geographic) is defined by the Earth's spin, and does not appreciably change over millions of years.
When did the south pole and north pole last switch?
The last magnetic pole reversal, when the north and south magnetic poles switched places, occurred about 780,000 years ago. This is based on geological evidence and the study of magnetic patterns in rocks and sediments.
True North and Magnetic North are the same true or false?
No. True north is the direction of earth's pole, 90 degrees north latitude. The pole is the axis upon which earth rotates. Magnetic north is the magnetic pole generated by the vast reservoirs of metal within the body of the earth. Magnetic north moves a little because the earth is very geologically active.
What is true north compared to magnetic north?
true north is the direction towards the Geographic north pole, the point on the globe exactly 90 degrees north of the equator, and thru which the earth's rotational axis meets the surface. Magnetic north is the direction towards the magnetic north pole which is predicted* to be located at 82.7 degrees north latitude, and 114.4 degrees west longitude (just north of Canada). Magnetic north is where a compass actually points to, so you must adjust your compass acordingly. *this is predicted because magnetic drift causes the pole to move from year to year.
When does the north pole become the south pole and the south pole become the north pole?
Answer The answer is no, of course not! It is the magnetic polarity of the earth that is being flipped, not the locations of Magnetic North and Magnetic South. Remember, 'Magnetic North' and 'Magnetic South' are locations, not magnetic poles. So even if their magnetic polarities flip, the names of the locations won't ever change! All that would happen is that the magnetic field would reverse, and your compass would point to Magnetic South instead of Magnetic North.Think of it this way, if the magnetic polarity of the earth flips, you wouldn't swap the names 'Arctic' and 'Antarctic'! So, why would you swap the names 'Magnetic North' and 'Magnetic South'!!!!!

How does compass work?
Its needle is a fine bar-magnet on a low-friction pivot to allow it to align itself with the Earth's magnetic field. Its North is therefore the Earth's magnetic, not rotational, North Pole, so a correction has to be made to the reading to establish the true geographical bearing. Since the magnetic pole slowly precesses over the years, the correction varies with time.
When did the south pole and north pole last switch?
The last magnetic pole reversal, when the north and south magnetic poles switched places, occurred about 780,000 years ago. This is based on geological evidence and the study of magnetic patterns in rocks and sediments.

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.
Who was north Ireland 10 years ago?
North Ireland is a geographical region not a person. There is also a country called Northern Ireland

What does true north refer to?
Every (about) 500,000 years, there is a magnetic reversal, which causes the poles to flip. The north becomes the south, and the south becomes the north. The true north is based on direction, not magnetic orientation.
When does the north pole become the south pole and the south pole become the north pole?

When discussing the Earth's magnetic field we could say that the Earth has a?
When discussing the Earth's magnetic field, we could say that the Earth has a geomagnetic north pole. The magnetic field changes every several hundred thousand years and thus the north and south magnetic poles swap places.
Why was the discovery of lodestones in Greece important to navigators hundreds of years ago?
Gave them magnetic north
Is the earths north magnetic pole wandering?
The Earth's magnetic poles do in-fact 'wander' over the years. Estimates put the movement of the North Pole at 34-37 miles (55 and 60 kilometres) per year. The magnetic poles are not always directly opposite each other. There is a good article on Wikipedia with more information - search for 'north magnetic pole'.
