How do we affect the Earth's magnetic field...?

#006 We all like good directions in life. It hurts when we come to know that someone has shown us a wrong direction. That can really make us angry. But wait! What if I tell you that we ourselves are tending to show the wrong direction to us!? Well, we tend to but, we cannot do anything for such a matter. Doesn't matter what we can do of it. The biggest question is, how do we do such an act? Well, you think of it by the time I explain Earth's magnetic field. Earth's Magnetic field The core of Earth is formed of molten Iron, Nickel and traces of Cobalt and other few metals. In molten state, the metals get ionized or the outermost electrons get excited out of bounds of the metal atoms. Now, imagine these electrons and ions as free charges. Due to the rotation of Earth about it's axis causes even these charges to revolve around their axis. And as per Ampere's and Oesterd's laws, moving charges cause magnetic field in the direction of their axis. They work on th...
