Which Phenomena Help Form Earth's Magnetic Field - Earth isn’t the only planet with a magnetic field; Web earth’s magnetic field is defined by the north and south poles that align generally with the axis of rotation (figure \(\pageindex{1}\)). But, magnets repel the same charged side, so why does north point north? Web earth’s magnetic field is generated by what’s called a “dynamo effect.” irregularities in a magnetic field. Web earth’s magnetic field, also known as the geomagnetic field, is a powerful, vital phenomenon that extends from the interior of the earth into outer space, where it interacts with the solar wind, a stream of charged particles emanating from the sun. The shape of the magnetic field is similar to that of a large bar magnet. Gas giant planets like jupiter have. Our compass magnets’ north end will point to the north part of the earth. The thermal and compositional currents moving within the liquid outer core, coupled with the earth’s rotation, produce electrical currents that are responsible for the earth’s magnetic field. Web the earth’s magnetic field acts much like a bar magnet with a north and south pole.

Earth isn’t the only planet with a magnetic field; The lines of magnetic force flow into earth in the northern hemisphere and out of earth in the southern hemisphere.
