Magnetic fields and the science of biblical creation

Hello Dr. Sarfati:
I have a couple of questions about Humphreys’s rapid decay model of Earth’s magnetic field. I couldn’t find anything on the CMI website that directly addresses these questions, but I apologize if I missed them.

One evolutionist I am debating argued that Lenz’s law implies that nature resists a change in magnetic flux. He used the example of “suddenly turn[ing] on a magnetic field going through a conducting loop, the loop will generate a current to form a magnetic field in the opposite direction to try and keep a magnetic flux of zero.” He says that “changing a magnetic flux generates an electromotive force that tries to oppose the change in flux” and used that to argue that fluctuation is much more likely than exponential decay when it comes to Earth’s magnetic field. Is his argument valid at all?

Also, is it true that if the magnetic field strength of the earth is decaying, its rotation speed must be increasing over time, to conserve angular momentum?

Thanks for your time and help.

Thank you for your response, it was very helpful. Regarding the second question, I understand what you mean about angular momentum, but the reason I asked it is the evolutionist I was debating said that “a magnetic field is angular momentum density,” and then went on to say that if the magnetic field was decaying, the angular momentum would have to “go somewhere” and would cause an increase in the rotation speed of earth. Is there such a connection between the magnetic field and angular momentum?

Thank you for your insight. I asked the evolutionist what formula he would use for the angular momentum of the earth’s magnetic field, and he said:

“You haven’t had any actual education in electricity and magnetism, have you? A magnetic field is angular momentum density. It’s given by c^-2(r x (E x H) ) r, E, and H being the vectors of the position, electric field, and magnetic field, respectively. Where would the angular momentum go [in Humphreys’s model of magnetic field decay]?” I also found a website that discusses this formula [Weblink removed as per our feedback rules—Ed.]. What am I missing?

The evolutionist also claimed that Lenz’s law would imply that “the nature of magnetism is oscillatory because Nature Abhors A Change In Flux,” and that the correct graph for Humphreys’s model would be a “damped oscillator” rather than an exponential curve. Is this correct?

By the way, I am granting permission to publish any of our email exchange on the CMI website if you wish to, I would just ask that you use my initials and not my full name if you decide to do so.

The link to support your site says that “They say the bible has been proven wrong by science. Whoever said that hasn’t been to creation.com.”

Hate to burst your bubble here guys, but I’ve been to this site, and I’m saying it. None of the “science” you’ve put up supports anything of creationism, and just goes to show that none of you really know what you’re talking about. The Bible does not classify as evidence. Not because it was written by people who weren’t there, but because it comes from the perspective of an imaginary being, God, who wasn’t there and to this day isn’t there. When I was a child, I believed in childish things such as God, the Devil, heaven, hell and angels. When I became older, I began to see reality as it really is, as opposed to the way I wanted it to be and put away those childish beliefs.

For your mental health, please do the same.

Thank you.

PS-The site has a good design, it’s just the content that sucks.
