“How the hell are you going to get enough power to generate 25 Tesla?”Given that we’re already , it shouldn’t be that big of problem. Building a superconducting coil big enough would be a bit of challenge though…“Given the difference in field strength, is there not a serious possibility of altering the Earths field permanently?”We’ve already created 25T fields and the magnetosphere is still doing its own thing. The magnetic fields we create extend a few hundred feet at most. The magnetic field itself is tens of thousands of miles across and is powered by a dynamo roughly the size of the Moon. |
