   Earth's magnetic field is useful for lot more than navigation by humans and various organisms. It is responsible for sustaining life on earth.

   Earth's magnetic field extends several 10s of 1000s of km into space, creating the magnetosphere, which protects Earth from the charged particles of the solar wind and cosmic rays that would otherwise strip away the upper atmosphere. Mars lost most of its atmosphere after its magnetic field shut down.
