I saw a show on this topic. Every once in a while the sun shoots out solar flares, these are made out of the suns material and are dangerous, they also go pretty far. Occasionaly one heads straight for earth, but the earths magnetic is strong enough to make a "shield" around the earth (sorry if this isn't enough detail).

The earth's magnetic field is important in that it prevents the sun's solar radiation from killing life on earth by wiping out the earth's atmosphere and deflecting dangerous radiation.
Earth's magnet field shields humans from dangerous radiation form the sun and protects the earth's atmosphere form the solar wind. Without the magnetic field, there would be no human life on earth.
Magnetic field doesnot have a half life. Elements have half life.
Directly : not at all. BUT It deflects the solar wind, thus the radiation levels on the Earth's surface is compatible with life; and there's still enough air for us to breath.
the radiation charges or ionizes the air in the upper atmosphere. the charged air conducts and acts like a wire passing thru a magnetic field which shields the earth from other particles and rays look for Van Allen belts
The earth's magnetic field protects the surface from getting struck by solar radiation.
it wil cancel the magnetic field whch will cause radiation from the sun to penitrate and kill off life on earth
All life on Earth are the children of Mother Earth.
Earths electromagnetic field is essiential to life on earth. Its deflects all the harmful radiation given off by the sun and in deep space. It is widely accepted that it is generated by our earths core. The core at the centre of the earth spins at a tremendous rate and the energy that it creates by doing this is thought to give of the electromagnetic energy.
effects of earth's magnetic field:-The sun emits huge amount of solid charged particles every time(called solar wind). if these particles are allowed to enter our earth, then there would be no chance of existence of life as this horrible effect of the solar wind would scrape away the atmosphere of our earth. but this magnetic field of our earth repels all these solid particles from the sun. by K.
