Not exact matches

Good for her Actual compasses are pretty good at giving you direction, as long as you realize that the north magnetic pole shifts quite often.

Which could account for our planet's weird history of magnetic field reversals, with north and south poles swapping places.

The poles have never completely reversed since, but for the past 160 years, the strength of the magnetic field has been decreasing at an alarming rate.

And in particularly in his latter part of his career, I mean the stuff that he was doing for example on magnetic mono poles still not verified, that's an absolutely beautiful piece of science; fundamental today in the way that quantum, advanced quantum field theory is done.

For every action, there's a reaction; every positive charge has a negative; every magnetic north pole has a south pole.

As far as we can tell, though, nature only supplies magnetic charges, or poles, in pairs — the inseparable north and south poles of the bar magnets beloved of school science demonstrations, for example.

SOLE POLE Scientists are searching for hypothetical particles called magnetic monopoles, which have a single north or south magnetic pPOLE Scientists are searching for hypothetical particles called magnetic monopoles, which have a single north or south magnetic polepole.

6 Reversal of Earth's magnetic field Every few hundred thousand years Earth's magnetic field dwindles almost to nothing for perhaps a century, then gradually reappears with the north and south poles flipped.

If orientated properly, a hot spot above the magnetic pole of the neutron star may whirl in and out of view for observers on Earth, producing a regular train of radio pulses separated by anything from a few milliseconds to a few seconds.

For instance electrical and magnetic forces have offsetting contributions; you might have a positive and negative charge or a north pole and south pole and those things tend to cancel out.

The records document that the Laschamp Excursion was characterized locally by (1) declination changes of ± 120 °, (2) inclination changes of more than 140 °, (3) ~ 1200 - year oscillations in both inclination and declination, (4) near 90 ° out - of - phase relationships between inclinations and declinations that produced two clockwise loops in directions and virtual geomagnetic poles (VGPs) followed by a counterclockwise loop, (5) excursional VGPs during both intervals of clockwise looping, (6) magnetic field intensities less than 10 % of normal that persisted for almost 2000 years, (7) marked similarity in excursional directions over ~ 5000 km spatial scale length, and (8) secular variation rates comparable to historic field behavior but persisting in sign for hundreds of years.

The magnetic poles on a neutron star act like fountains, an escape valve for charged particles that get trapped in the star's enormously strong magnetic field.

For instance, the models suggest that around 1 billion years ago, Earth may have transitioned from a strong dipolar field to a weak magnetic field that fluctuated wildly in terms of intensity and direction and originated from several poles.

There would presumably be a partner for the third pole, since magnetic poles always come in pairs, he adds.

He says some theoretical models have previously attempted to account for the primary and secondary pulses as coming from the leading and trailing edges of a cone of emission from just a single magnetic pole.

Fortunately, 2012 leaves all that phooey to a crazy pirate radio guy but instead invents its own crackpot reason for the Earth's destruction in the form of mutated neutrinos from the Sun that act as microwaves on the planet's core, which in turn heat it causing the Earth's crust to shift wildly and the magnetic poles to move.

According to the prevalent theory for the moon's formation — the «giant - impact hypothesis» — the Earth's axis (the invisible line that runs through the planet and connects its two magnetic poles, around which the planet spins each day) used to run perpendicular to its orbit.

They were part of a small and remarkable community of tough, determined explorers and researchers for whom the poles are almost unavoidably magnetic.

Compounding this would be a weaker geo magnetic field which would allow more galactic cosmic ray penetration into the atmosphere, while perhaps causing excursions of the geo magnetic poles to occur in that they would be in more southern latitudes concentrating incoming galactic cosmic rays in these southern latitudes where more moisture would be available for the cosmic rays to work with, making for greater efficiency in the creation of clouds.

The planets may have a spin - orbit coupling effect on the Sun which affects its rotation rate, which would then affect the solar dynamo and sunspot production, and therefore the build up of magnetic flux at the poles, and the length of a solar cycle: if the solar cycle is weaker with less sunspots, it'll take longer for the build up of opposing flux to reach the point when it flips the poles.

Paramagnetic oxygen has been influenced by wandering magnetic poles for 2300 million years.

«If the rush to the poles fails to complete, this creates a tremendous dilemma for the theorists, as it would mean that Cycle 23's magnetic field will not completely disappear from the polar regions.

And for winnipegman: The position of most of North America relative to the rotational or geographic north pole (the magnetic north moves around) is well understood.

The records document that the Laschamp Excursion was characterized locally by (1) declination changes of ± 120 °, (2) inclination changes of more than 140 °, (3) ~ 1200 - year oscillations in both inclination and declination, (4) near 90 ° out - of - phase relationships between inclinations and declinations that produced two clockwise loops in directions and virtual geomagnetic poles (VGPs) followed by a counterclockwise loop, (5) excursional VGPs during both intervals of clockwise looping, (6) magnetic field intensities less than 10 % of normal that persisted for almost 2000 years, (7) marked similarity in excursional directions over ~ 5000 km spatial scale length, and (8) secular variation rates comparable to historic field behavior but persisting in sign for hundreds of years.
