Question

Magnetosphere of the earth is a result of rotation. Explain .​

Answer 1

Answer:

It means the generation of a magnetic field due to rotating current. This electric current is a result of the spiral eddies generated due to earth's rotation and vertical currents formed due to the temperature difference between the outer core and inner core.

Answer 2

Answer:

The temperature difference between outer and inner core results in vertical currents. The Earth’s rotation give them circular motion while the electric currents develop in spiral eddies of liquid iron generates magnetic field. This process is called geo-dynamo. This magnetic field of earth is effective outside of Earth’s surface for quite a distance hence it acts as a protective shield against solar winds coming from sun and region which is surrounded by magnetic field is called magnetosphere which is caused by the Earth’s rotation
