Stop the Train! Magnetic Brakes for a Maglev Train
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.) WebThe physical energy needed to stop the bullet could be calculated by the Lorentz law. You would need two perpendicular fields. One would induce the a current in the copper, the other would exert a force on the conductor. The problem is that you won't have a return path for the current if you assume a linear dimensionless bullet. how long are days on mercury
