Origin and Destiny of the Earths Magnetic Field (ICR Technical Monograph, No. 4) (Buy Now)

Thomas G. Barnes

The most remarkable worldwide geophysical property in the last century is the rapid decay of the earth\'s magnetic field.  As a consequence of this decay the earth is losing the magnetic shield that has provided protection from harmful radiation.  The author supplies an answer to the question:  When will the magnetic field vanish?

The source of the earth\'s magnetic field has been a problem to evolutionary scientists because the best data, the real-time dat (130 years of data) do not fit their traditional geochronology.  the author shows that these data do support the theory first proposed by Sir Horace Lamb.  That theory is up-dated and the real-time data employed to evaluate the half-life of the earth\'s magnetic field.  Extrapolated values of the earth\'s magnetic field at dates in the past are then compared with stellar magnetic fields to arrive at a plausible limitation on the age of the earth\'s magnetic field.

An elementary discussion of the pertinent physical principles is included.  Further use is made of the up-dated theory to provide new insights into the properties of the core of the earth.  An evaluation is made of the electrical conductivity of the earth\'s core.  This conductivity is compared with that of certain metals at high temperatures for clues to the type of material in the earth\'s core.  A computation is made of the value of the electric current presently flowing in the core and the resultant rate of heating which it produces in the earth.

The most profound consequence of this theory of the source of the earth\'s magnetic field and the observed data is that it demands a recent origin.  There is no uniformitarian means by which the phenomenally large current required to produce the earth\'s magnetic field could have been started in recent geologic time.  The conclusion is reached that the earth\'s magnetic field is the result of the Biblical creation.
