Mysteries of Earth's magnetism to be mapped

Many mysteries remain about the Earth's Magnetic Field. It has been known in China since the Qin dynasty, found its way to Europe in medieval times and used for ocean navigation. The frozen lava record at the mid-ocean ridge has shown periodic rapid flips of the north and south magnetic poles. Its interaction with solar particle flux has been deemed critical to climate variability and the evolution of life on earth. Research continues.

BBC News - Esa's satellite Swarm launch to map Earth's magnetism

The Swarm mission to map the Earth's global magnetic field in unprecedented detail has launched from Russia. The trio of European Space Agency (Esa) satellites left the Plesetsk Cosmodrome at 12:02 GMT, riding a Rockot vehicle. They were deployed at an altitude of 490km, in a polar orbit, 91 minutes later. Swarm's data should help scientists understand better how the field is generated, and why it appears to be weakening. The strength has fallen by some 15% in the past two centuries. The movement of the north geomagnetic pole has also accelerated.

Time to flip?

Perhaps the decline is no more than a magnetic 'jerk'. But it could also be the prelude to a looming geomagnetic-field reversal. Geophysicists know from analyses of volcanic rock — which records the direction of the magnetic field at the time it solidified from lava — that Earth’s polarity last flipped some 780,000 years ago. “A reversal is overdue, if you will,” says Friis-Christensen.
The weakening, he says, is probably the result of changing currents and vortices in the planet's outer core, an ‘ocean’ of molten iron that slowly whirls around a solid, inner core. Swarm's data should help to improve computer models of these currents and to provide more-informed projections about the evolution of the geomagnetic field, says Richard Holme, a geophysicist at the University of Liverpool, UK. “Earth’s magnetic field is still a bit of a mystery,” he says. “Swarm could shed light on many questions, and it will open up a completely new window on previous data and historical records.”

 nasa discovers hidden portals in earth's magnetic field

NASA used its THEMIS spacecraft, as well as a European Cluster probe, to examine this phenomenon. They found that these portals open and close dozens of times each day. It’s funny, because there is a lot of evidence that points toward the sun being a giant star gate for the ‘gods’ to pass back and forth from other dimensions and universes. The portals that NASA has discovered are usually located tens of thousands of kilometres from Earth and most of them are short-lived; others are giant, vast and sustained.
As far as scientists can determine, these portals aid in the transfer of tons of magnetically charged particles that flow from the Sun causing the northern and southerns lights and geomagnetic storms. They aid in the transfer of the magnetic field from the Sun to the Earth. In 2014, the U.S. space agency will launch a new mission called Magnetospheric Multi scale Mission (MMS) which will include four spacecraft that will circle the Earth to locate and then study these portals. They are located where the Earth and the Sun’s magnetic fields connect and where the unexplained portals are formed.

  A NASA-sponsored researcher, Professor Jack Scudder, at the University of Iowa has developed a way for spacecraft to hunt down hidden magnetic portals in the vicinity of Earth. These portals link the magnetic field of our planet to that of the sun.

Dr. Scudder received his PhD in Plasma Physics from University of Maryland, and is a theorist who interacts with experiments about the physics of space magneto-plasmas and their kinetic properties - especially Knudsen regime and collisionless transport in the: solar corona, solar wind, collisionless shocks, magnetosheath, magnetopause, collisionless reconnection, the plasmasphere, magnetosphere. Analytical and numerical solution of MHD, Boltzmann, and Vlasov equations and design and interpretation of spaceborn particle detectors.

 Earth’s Magnetic Field and Climate Variability

The locations of the magnetic poles are not static and continuously change position. The following figure (left) shows (magenta) the path of the North Magnetic Pole (NMP) since its discovery in 1831 to the last observed position in 2001, and (purple) past NMP positions since approximately 1600 derived from spherical harmonic models. [http://gsc.nrcan.gc.ca/geomag/nmp/long_mvt_nmp_e.php] The figure illustrates that the position of the NMP given for a particular year is an average position – it wanders daily around this average position and, on days when the magnetic field is disturbed, may be displaced by 80 km or more. Although the daily motion on any given day is irregular, the average path forms a well-defined oval due to interaction with the sun’s magnetic field.
