Question

magnetosphere of the earth is a result of rotation. explain.

Answer 1

It is a well-known fact that Earth has a powerful magnetic field with both South and North poles.

The magnetic field of the earth is to be produced deep down in the core of Earth. It is what causes earth’s magnetic field.

The rotation axis is entirely different from magnetic poles.

The big variation creates some force for the globe for rotating on its own axis.

This similar technique is a case with every planet in the huge Solar System.

Answer 2

1) The outer core of the earth's interior is in a liquid state and the proportion of iron is more in this layer.
2) The density of outer core is 9.8 gm/cm. The temperature of the liquid outer core is around 5000 degree celsius. Whereas the temperature of inner core is equivalent to the surface temperature of the sun.
3) The difference between the outer and the inner core gives rise to vertical currents. The earth's rotation gives them eddy (circular) motion. Electric currents develop in these spiral eddies of liquid iron and thus magnetic field is generated. It is sometimes called geo-dynoma too. This magnetic field of the earth is fictional even outside the earth's surface for quite a distance.
4)As a result, a cover develops around the earth's atmosphere and is protected from solar winds coming from the sun. The magnetic field thus developed around the earth, is called magnetosphere.
