    Something to do with the molten iron in the core?

    its to protect us from harmfull ionising particles in the black of space. this was a key feature , of the earth. if we didnt have a a magnetic field life wouldnt exist. since the earh would be too harsh of an environment.
    i think its aused by the movement of the iron core. mind u they say the it gona change polarity soon. soo watch out. lol

    Soon? What proof do you have? That we are past the half life of the polarity life? Anyone who knows anything about continious stats would know that we are as likely for the polarity to switch now as it was 10000 years ago. Besides, do you even know what sort of tim scale "soon" means in geology? Even if it starts today, I'm not sure if it will even affect my lifetime.
