I woke again with a question
The earth has a magnetic field that shields us from nasty radiation,
It does not seem that strong at the surface
two questions,
a) I wonder how much power / magnetism would be needed to protect enough of a space ship to enable the crew to be protected ?
say 3m by 3m by 3m
b) inside a magnet, is there a north south ? i.e. if the space ship was "magnetised" some how, would all the ferrous bits inside get magnetised ?
