The Curie temperature that affects magnetic fields is a thing, but it doesn't apply to how the Earth's magnetic field is created. You are thinking of the effect as it applies to a permanent magnet, which is to say a material that has been made magnetic through natural or artificial means. The magnetic field in say a neodymium magnet is not self generating. It was applied to the neodymium ceramic material by an electromagnet at the time of manufacture. The material aligns its magnetic domains to the field created by the electromagnet and retains that alignment unless heated beyond the material's Curie point where the domains will return to a random alignment. You can basically magnetize and demagnetize magnets with a strong electromagnet and heat.
The magnetic field of the Earth is not created by simple domain alignment in a solid material. The interactions of the materials of the core layers, mainly iron and nickel, cause electromagnetic fields by Eddy Currents forming in those regions. It is an electromagnetic process by which the Eddy currents give rise to the magnetic field just as an electric current flowing through a wire creates a magnetic field around it.. The Earth is more akin to an electromagnet than a permanent magnet. You can't demagnetize an electromagnet by the application of heat in the same way as a permanent magnet could be. They are just two different kinds of magnets and only one is affected by the Curie temperature. Does that make sense now?
Makes sense, yes. Thanks
Would you know anything about scaler waves? I heard a guy Braden and a Heavysides talking about them years ago. Cant seem to wrap my head around how to generate them, where they are found or what use they have.
Glad to help out.
I don't know anything about scalar waves, but since it has come up a few times in this thread, I should probably go learn about them.
What I remember is basically electronic waves and micro/radio....waves have a sine and cosine function.
Well scaler waves dont really. it's like having a long piece of rebar and you wack it at the end with a hammer laterally; the result is instant at the other end. That was the analogy if I remember it correctly.
