How does earth produce a magnetic field
WebApr 8, 2024 · Scientists know that today the Earth’s magnetic field is powered by the solidification of the planet’s liquid iron core. The cooling and crystallization of the core … WebActually, it's possible to use the Earth's magnetic field to generate electricity. A satellite in the form of large diameter loop in orbit around the Earth will generate a current in that loop, and could be used to power something, but at the cost of a rapidly degrading orbit.
