Correct answer: Magnetic field is created when molten material is heated from earth's core.
Due to the movement of molten iron and nickel inside the core of the earth magnetic field is generated. Due the the generation of high temperature all the molten material are in the liquid form. A Coriolis force is generated due to flow of molten liquid, which result in the formation of magnetic field.
The magnetic field of the earth is used to protect the earth from the harmful solar radiation .
Answer:
Option A
Explanation:
Corona is defined by the strong magnetic fields. When these strong magnetic fields confine solar atmosphere and produces violent bubble of gases then it is said to cause coronal mass ejection (CME).
When a CME passes through the solar wind, it causes production of high velocity solar energetic particles that follow magnetic field lines and passes through the space between the Sun and the Earth. The charged particle added by CME intensifies the solar wind.
Hence, option A is correct
