Why it is important
Without the magnetic field earth would not have life on it today.
The magnetic field is our first defense against many cosmic rays and solar flares.
Plasma is deflected by magnets so the field helps protect us from the suns solar wind.
Solar wind is made up of charged electrons and protons (plasma) and constantly streams towards earth.
This plasma will be repelled when it comes in contact with the field and gets pushed to the side and around the magnetic field.
Below is a video explaining this effect:

Since life cannot exist in a high radiation environment the magnetic field helps deflect these radioactive rays and particles keeping our home radiation free and allowing life to thrive.
