The earth and many other planets, and even the sun, currently retain very strong magnetic fields. Over time those magnetic fields should have weakened. Is there a phenomenon that can recharge dying magnetic fields? How are these magnetic fields formed? Are magnetic fields formed naturally or designed by God for our protection? How do the magnetic fields really affect earth? What does the evidence tell us about the age of the earth and the universe?
The earth is approximately 4.5 billion years old and its magnetic field is due to the movement of charged metals within the earth’s liquid outer core. This moving of charged metals will always form a magnetic field around them naturally. The earth formed with swirling currents of hot, molten rock, which simultaneously created magnetic fields associated with the swirling mass. So the earth has always had a strong magnetic field, and for that matter, magnetic fields have probably formed around most, if not all, other astronomical objects as well. The human body even has a slight magnetic field. The earth’s magnetic field has a positive impact on this planet as it shields harmful solar and celestial radiation from entering our atmosphere.
Over earth’s history, the chaotic currents are like a “dynamo” inside the earth, which is always moving and causing the magnetic field to change constantly and these “magnetic fields morph and push and pull at one another.” From ocean sediment cores and surveys and the fossil record, magnetic fields are recorded in the rocks and specifically show that the poles even occasionally flip, making the north pole the south pole and then back again. This pole reversal happens “about every 200,000 to 300,000 years, although it has been more than twice that long since the last reversal.” “Scientists estimate reversals have happened at least hundreds of times over the past three billion years,” and each reversal may take a few thousand years. Fortunately, these pole reversals don’t appear to cause environmental problems or exposure to harmful radiation , since there still is a magnetic field, it is just changing.[i]
The earth’s magnetic field has actually weakened by 10% since the 19th century, but University of California professor Gary Glatzmaier says that “the field is increasing or decreasing all the time.” “We know this from studies of the paleomagnetic record.” He also explains that that 10% is a relatively small amount of change and that “Earth’s present-day magnetic field is, in fact, much stronger than normal…twice (as much as) the million-year average.”[ii]

Is the above correct? Do you evolutionists agree with this position? I have tried to write it as you believe it. Do you have any disagreements or concerns or additions?
Before commenting, please read the following disclosures.
Any offensive language will automatically disqualify your comment for publication, even if the arguments contained are good. Please comment on the ideas that are presented and not the presenter. If your comment becomes an ad hominem argument and does not substantially address the issue, your comment will be disqualified as well. We are looking for real arguments, not fallacious ones, so that we can present and challenge opposing ideas and arguments as they are truly believed by evolutionists. We do not want to tear down straw men as well as you do not want to be misrepresented. Also, please keep your comments as brief as possible, and if the majority of the comment does not address the current issue, but becomes a red-herring, it will not be posted as well. If your comment does not fall into one of the above restrictions, then your comment will be posted unedited (you may want to check your spelling, grammar, etc.) We thank you for your time and comments.
One thing to keep in mind, each blog is one piece of evidence. Evidence has to then be interpreted, which is not a fact…but evidence strengthening or weakening a specific hypothesis or theory. So there can be multiple ways of interpreting the same evidence. I am not being unscientific, but asking more questions and being skeptical is being more scientific. I am still working on these, so please help with your comments.
