I doubt that you really mean that. :)
The magnetosphere stops the solar wind stripping Earth's atmosphere away.
Unlike Mars, that lost its magnetosphere and little of the atmosphere
The solar wind consists of ripped-apart atoms (called plasma) flying
out of the Sun. This is mostly hydrogen, that is, bare electrons and
protons, with a little bit of other kinds of nuclei, mostly helium.
The space between solar systems is similar, but they come from other
stars in our galaxy. These charged particles can be redirected by
magnetic fields; for instance, Earth's magnetic field shields us from
So the earth magnetosphere should deflect most of the solar wind.
