“The Earth's magnetic field is in a weakening stage right now. Data collected this summer by a European Space Agency (ESA) satellite suggests the field is weakening 10 times faster than scientists originally thought. If the magnetic field weakens enough, then the Earth could be hit with dangerous amounts of solar radiation and cosmic rays ….”

Now this news gives us some food for thought:
If the earth's magnetism is due to a permanent magnet it would have been destroyed by now since a permanent magnet gets destroyed by high temperature (and we know that the earth's core is too hot as compared to the earth's surface). Further, since the earth's magnetic field is of the value of 8x10 (to the power 22) ampere meter squared, which is a very large number, the earth magnetic field must be utilizing a very large supply of energy to keep this going. From where did this energy come in the first place? No scientist has reached any conclusion on this and it is a mystery for them. (There are different theories without conclusion.)
The earth's magnetic field is due to an electric current circulating in the core of the earth. After this current started flowing, this current starts decaying as per Lenz's Law and it takes thousands of years to decay taking the earth's parameters into account. It is also found that the time taken for decay is proportional to the square of the radius. Hence when calculated, the dying out takes a few thousand years only and not millions of years. Now it has also been discovered that there is about 810 megawatts of power being used by the earth's magnetic field which is equivalent to the production of a huge power plant on the earth.
The evolutionists have been unable to answer the question of FROM WHERE THIS POWER HAS BEEN FLOWING FOR BILLIONS OF YEARS if their evolution theory is to be accepted. There is obviously a huge missing link somewhere. The currents are still flowing but it is estimated that it is decaying at an annual rate of approximately about 5 percent.
This leads us to believe that the earth’s magnetic field is only a few thousand years old and it will again revert back to its original state after a huge nuclear catastrophe even as the earth's axis will also change because of the huge nuclear explosions . The huge magnetic energy to the original state will be derived from the nuclear explosions.
That means history has been repeating:
appearance of civilization climaxed by a huge nuclear catastrophe,
again appearance of civilization climaxed by a huge nuclear catastrophe,
again appearance of civilization climaxed by a huge nuclear catastrophe …… ……………………………….
