Determination of the earth’s magnetic field
Our planet's magnetic field is believed to be generated deep down in the earth's core nobody has ever taken the mythical journey to the centre of the earth, but by studying the way shockwaves from earthquakes travel through the planet, physicists have been able to work out its likely structure. There are three important force fields associated with planet earth, a gravitational field, an electric field, and a magnetic field the gravitational field attracts us to the earth, preventing us from flying off into space as the earth rotates. Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the earth's interior to where it meets the solar wind, a stream of charged particles emanating from the sun.
