| After some 400 years of relative stability, Earth's north magnetic pole has started moving again. |
|
| At the present rate, the north magnetic pole could swing out of northern Canada into Siberia. |
|
| The north magnetic pole, to which compass needles point from all over the Earth, moves day by day. |
|
| The magnetic pole was first determined in 1831, hundreds of miles from its present location. |
|
| Therefore the earth's south magnetic pole is located near the geographic north pole and is called the geomagnetic north pole. |
|
| When magnetic pole reversal finally happens, life on earth could be dramatically affected. |
|
| On May 31, 1831, Ross located the position of the north magnetic pole on Boothia Peninsula in northern Canada. |
|
| A unipolar sensor basically acts as an NPN transistor whose base current is on when the device is in the presence of a south magnetic pole. |
|
| Visitors learned how magnetic storms affect satellites, and how the magnetic pole is constantly changing. |
|
| The magnetic pole pointing toward the North Magnetic Pole is the magnet's north-seeking pole, or north pole, for short. |
|
| The south-seeking pole, or any pole similar to it, is called a south magnetic pole. |
|
| The magnetic pole pointing toward the South Magnetic Pole is the magnet's south-seeking pole, or south pole, for short. |
|
| The declination of the magnetization further reveals the direction to the magnetic pole at the time of the magnetization. |
|
| 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. |
|
| The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole. |
|
| The Earth is like a big magnet, with lines of magnetic force coming out of its surface near one magnetic pole, looping out into space and diving back into the ground at the other magnetic pole. |
|
| According to Hansteen, a magnetic pole is not a point where the magnetic field is vertical, nor is it a point towards which a compass needle points. |
|
| Because the northern magnetic pole is in Canada, over most of the country these lines of force are crowded together and diving into the ground at steep angles. |

|
| Hansteen believed that the observed pattern of the magnetic field could be explained by two magnetic axes, each with two poles, but his definition of what constituted a magnetic pole differs from the definition we use today. |
|
|
|
| While the Northern Lights can sometimes be seen as far south as the United States, the closer you get to the Earth's magnetic pole, the better your view will be. |
|
| As the north magnetic pole is approached in the Arctic, the horizontal component becomes progressively weaker until at some point the magnetic compass becomes useless as a direction measuring device. |
|
| The magnetic pole of the North which draws us together as Canadians in an imaginative way, allows us to treat each other with decency, respect and to attempt to understand the needs of others. |
|
| In 1909 Sir Ernest Shackleton reached the south magnetic pole. |
|
| You represent the magnetic pole of the Hierarchy on earth. |
|
| As you will soon find out, Canada's proximity to the northern magnetic pole is the main reason we see a predominantly Canadian random act of nature called the Aurora Borealis, or Northern Lights. |
|
| Furthermore, paleomagnetic data had shown that the magnetic pole had also shifted during time. |
|
| At some point close to the magnetic pole the compass will not indicate any particular direction but will begin to drift. |
|
| The goal of this expedition was to navigate to the North Magnetic Pole by traditional means using a sextant and an astrocompass. |
|
| The competitors who travel by foot and skis pulling sledges with supplies, will cover over 350 miles in four stages from Resolute Bay, Canada, to the North Magnetic Pole. |
|
| Led by accomplished Polar explorer Jim McNeill, the group will pull sledges weighing up to 250 lb for up to 10 hours a day 210 miles to the Magnetic Pole. |
|
| He, along with his expedition, made the first ascent of Mount Erebus and the discovery of the approximate location of the South Magnetic Pole. |
|
| If the data indicate that the North Magnetic Pole were near the South Rotational Pole, the strata would exhibit reversed polarity. |
|
| After the North Magnetic Pole was located in 1831, explorers and scientists began looking for the South Magnetic Pole. |
|
| It continues to rotate upwards until it is straight up at the South Magnetic Pole. |
|
| During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. |
