Geomagnetic storms result when the pressure of plasmas contained inside the magnetosphere is sufficiently large to inflate and thereby distort the geomagnetic field.
32.
During a geomagnetic reversal the geomagnetic field becomes weaker, and stays weak for thousands of years during the transition to the opposite polarity.
33.
The primary control experiment confirmed that the majority of the nest had a preferential exiting angle in accordance with the local geomagnetic field.
34.
The average geomagnetic field is about 450 mG and is inclined by about 45?with respect to the horizon at the detector site.
35.
Several advanced geophysical experimental facilities are housed in EGRL . It houses magnetometers for measuring geomagnetic fields, varieties of radars and weather stations.
36.
Because cosmic rays are also influenced by the geomagnetic field, difficulties in reconstructing this field set a limit to the accuracy of the reconstructions.
37.
For example, the variations in the geomagnetic fields can be to the order of several aT where 1aT = 10 " 18 T.
38.
But if it's true, it could explain several puzzles about the geomagnetic field, which is generated by turbulent currents of iron in the outer core.
39.
Several ant species, including fire ants, have been shown to contain ferromagnetic nanoparticles that may contribute information about the geomagnetic field for orientation during foraging or migration.
40.
In the presence of the geomagnetic field an electric field is generated in a rotating on frame of reference in order to compensate for the Lorentz force.
