Web3 Answers. No. The point of a Faraday cage is that it's made of a conductor, which responds to electric fields. A strong magnetostatic field is different, and will barely be affected by the Faraday cage. (The cage may have some magnetic properties, but that's not what makes it a Faraday cage, and it's unlikely to have a significant impact.) Web7 mrt. 2024 · The magnetic field extends out into space forming a “bubble” in which the Earth sits. This magnetic bubble shields the planet’s atmosphere from the Sun’s magnetic field, which otherwise would strip away Earth’s atmosphere over billions of years.

Web3 dec. 2024 · Earth’s Magnetic Field. Earth’s magnetic field, albeit generated approximately 2,000 miles below the surface, protects the planet’s atmosphere from space radiation and solar wind.
