Earth’s Rapidly Decaying Magnetic Field Says the Earth is Young

One of the most powerful evidences for a young earth is its rapidly decaying magnetic field. Measurements taken from 1835 to 1965 reveal that the earth lost a whopping 8% in its magnetic field strength over those 130 years.1) More recent measurements confirm this exponential rate of decrease, at a rate of about 1.5% every 30 years.2) That means if you are 60 years old, in your own lifetime, the earth’s magnetic field decreased in strength by about 3%. Let us be glad the earth is not decreasing in size at such a rate! That is an astounding rate of loss for a planet-wide feature, which the old-earth paradigm requires to be billions of years old.

  1. [1] “Following Gauss, scientists continued to make global measurements of the field. Four decades ago, Keith McDonald and Robert Gunst (1967, 1968) compiled the results of such measurements from 1835 to 1965. They drew a startling conclusion: during those 130 years, the earth’s magnetic dipole moment had steadily decreased by over 8 percent!” (Humphreys, “Earth’s Magnetic Field,” (CRSQ 47, 2011), 194 

  2. [2] “Over those thirty years [1970 to 2000], about half of the energy that was lost from the dipole was transferred into multipole fields (up to ten pairs of magnetic poles of decreasing energy that point in different directions). However, the bottom line is that the overall energy of the entire field, which includes the energy of the dipole and all multi-pole fields, decreased by at least 1.25%, and perhaps as much as 1.57% (Humphreys, 2002)… If this rate of loss holds steady, then the field will lose half of all its energy in approximately 1500 years.” – (EMM, 17-18
