Tao, It is known that the earth's magnetic field is decaying faster than any other worldwide geophysical phenomenon. A comprehensive ESSA Technical Report1 gives the values of the earth's magnetic dipole moment (the vector which gives the strength and direction of the magnet) ever since Karl Gauss made the first evaluation in 1835. The evaluations have been made about every 10 or 15 years since then. Each evaluation required accurate worldwide readings over an epoch (a year or so) and special mathematical reduction to "wash" out the "noise." These reliable data clearly show this relatively rapid decay.
The earth'a magnetic field is similar to a dipole magnetic field, but deformed by the action of the solar wind.
In most places in the world, the Earth's magnetic field has decreased over the last century. Magnetic reversals occur (relatively) quickly.
A relatively recent NASA satellite preliminary report shows a rapid decay in the earth's magnetic field. No knowledgeable scientist debates the fact of the rapid decrease in the earth's magnetic field, nor does he question that the associated electric current in the core of the earth is using up energy.
Earth's magnetic field is actually weak, varying from less than 0.3 gauss in most of South America and South Africa, to over 0.6 gauss around the magnetic poles. In comparison, a small iron magnet is about 100 gauss, a small Neodymium-iron-boron (NIB) magnet is about 2 000 gauss, and a big electromagnet is about 15 000 gauss.
After the first release of the first ring wave from the sun, last may, there were no sun spots. Sunspots are relatively cool spots on the suns surface, however when a ring wave is released, it causes the sun to intensify to the point that there are no cool spots.
