Not exact matches
The farther away from Earth you get, the more its
magnetic field actually does act
like a
dipole, or a bar magnet — even if in reality it is no such thing.
And here's something to add even more confusion to the north
magnetic pole (aka dip pole) versus north geomagnetic pole (aka
dipole): the
magnetic pole in Earth's northern hemisphere acts
like the south pole of a bar magnet.
A unique property of the molecule is the large permanent
dipole moment, which reacts with an electric field much
like a bar magnet reacts with a
magnetic field.
hengav (00:25:44): What I became alarmed at were graphs
like: http://www.ngdc.noaa.gov/stp/GEOMAG/image/aastar07.jpg There are three factors that contribute to the trends seen in the Figures you cite: (1) the aa - index is too low before 1957, see http://www.leif.org/research/Analysis%20of%20K=0%20and%201%20for%20aa%20and%20NGK.pdf (2) the sunspot number is too low before 1946, see http://www.leif.org/research/De%20maculis%20in%20Sole%20observatis.pdf (3) the Earth's
dipole magnetic field has decreased 10 % the last 150 years.
When it is noticed that Venus is potentially losing its Atmosphere at a rate related to overall gravity well determinations and the Atmospheric density is potentially due to loss of a planetary «
magnetic dipole» with then a relationship linking the notice of which «Planets» in this Solar System present «Earth -
like Dipoles», the CONTINUANCE of «life as we know it» is NOT in any study of a supposed «greenhouse effect» or even other Planet's Atmospheres.
