This might sound silly but...If you produce a magnetic field of large magnitude, does it locally distort the Earth's magnetic field? I figured that it might, but I didn't know how to go about analyzing it.
and 2, you get pretty northern lights in the north ( and presumably the south?
i"m new at the forum, but already i fell like i"m being tossed to the lions every time i ask a question. not so much here as other places on PF. but as Albert said " i"m passionately curious " so i"ll press on. does anyone know weather a magnetosphere is made up of individual magnetic lines or layers of magnetism like the layers of an onion or maybe fins? i really would like to know. thank you, gravity guru.

Here's a good one for boffins here to mull over:
In the film The Core some idiots drilled into the Earth's core and set off some nuclear explosions to try to stop the Earth's magnetic field from reversing. But imagine that the Earth's magnetic field really was reversing ... what would be the best way to prevent the impending doom, how would you stop the reversal?
As a matter of interest I can tell you what a geophysics lecturer told me on the subject of preventing a magnetic field reversal ... Apparently, if we set up a large chain of exercise bikes around the equator and used them to generate a current, this would stop the field from reversing ... How this works exactly I must admit I do not know ...Re-introduce lead baised paint :p
destari, ulysees and carlos, thank you for replying. i don"t mean to be cryptic but this time of year i begain to get busy , because of storm season, so it takes up most of my time but i"ll try to be somewhat clearer. i need to say,at frist, that i was taught that a charge must move before a magnetic field could be formed and with that in mind i looked at the Earth and thought it should apply here as well. meaning that the earth"s magnetic field lags behind the rotation of the Earth and also rotates at a slower speed . it takes several weeks for the lagging manetic field to travel from the cape verde islands to the west indies, this is based on the time it takes storms to travel that distance. anyway, time delay would produce relative motion at some rate. and the field would act like a charge vaccum, cleaning up and building up as it goes. this to me made sense. gavity guru.
there are external influences, such as magnetic storms (which have nothing to do with storms in the meteorological sense),
