Magnetism is a force that acts at a distance and is caused by a magnetic field. This force strongly attracts ferromagnetic materials such as iron, nickel and cobalt. In magnets, the magnetic force strongly attracts an opposite pole of another magnet and repels a like pole. The magnetic filed is both similar and different to an electric field. The lines of magnetic flux flow from one end of the object to the other. Although individual particles such as electrons can have magnetic fields, larger objects such as a piece of iron can also have a magnetic field, as a sum of the fields of its particles. If a larger object exhibits a sufficiently great magnetic field, it is called a magnet. When two magnetic objects are close to each other, there is a force that attracts the poles together. But when two magnetic objects have like poles facing each other, the magnetic force pushes them apart.

We also concluded that Magnetism has a region around the Earth where they dominate the environment, that contains a mix of electrically charged particles, electric and magnetic phenomena rather than gravity determine its structure called magnetosphere. Lots of factors that happen on the ground come from the magnetosphere: fluctuations of the magnetic field known as magnetic storms and sub-storms, and the polar aurora or "northern lights", appearing in the night skies of places like Alaska and Norway.
The nature of magnetism was basically a force between electric currents: two parallel currents in the same direction attract, in opposite directions repel. In nature, magnetic fields are produced in the rarefied gas of space, in the glowing heat of sunspots and...
