- Earth has magnetic poles because of charged-particle currents roiling deep within its molten core.
- The magnetic poles are different from geographic poles, the surface points marking the axis of Earth's rotation.
- The magnetic poles were perpendicular to its rotational axis.
- After some 400 years of relative stability, Earth's north magnetic pole has started moving again.
- A really smart Englishman named William Gilbert proposed sometime in the early 17th century that the Earth itself was a giant magnet and that its magnetic poles were some distance from the Earth's geographic poles.
- Scientists have long known that magnetic poles migrate and in rare cases, swap places.
- While the true North and South poles represent the geographic points around which the Earth rotates, the magnetic poles are the projection onto the surface of the axis of the Earth's magnetic field.
- The magnetic poles or dip pole are computed from all the Gauss coefficients using an iterative method.
- Therefore the earth's south magnetic pole is located near the geographic north pole and is called the geomagnetic north pole.
- The earth's north magnetic pole is drifting from North America at such a clip that it could end up in Siberia in the next 50 years, scientists said Thursday.
- Evidence from rocks of the same age in different continents indicates different ancient positions for the earth's magnetic poles.
- Like Earth, the Sun has magnetic poles, but unlike Earth, the Sun's polarity is not constant.
- The magnetic pole was first determined in 1831, hundreds of miles from its present location.
- Even at the present time, while the Earth's magnetic field is relatively stable, the location of the magnetic poles is slowly shifting.
- At the present rate, the north magnetic pole could swing out of northern Canada into Siberia.
- Charged particles are attracted to Earth's magnetic poles.
- Second, the magnetic field is constantly changing, and this means that the magnetic poles are constantly in motion.
- Every 11 years the Sun reaches a peak of activity that triggers the magnetic poles to exchange places.
- On May 31, 1831, Ross located the position of the north magnetic pole on Boothia Peninsula in northern Canada.
- When magnetic pole reversal finally happens, life on earth could be dramatically affected.
