SOLAR SYSTEM

Detailed explanation-1: -Generated by the motion of molten iron in Earth’s core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun. It also provides the basis for navigation with a compass.

Detailed explanation-2: -The Earth’s outer core is in a state of turbulent convection as the result of radioactive heating and chemical differentiation. This sets up a process that is a bit like a naturally occurring electrical generator, where the convective kinetic energy is converted to electrical and magnetic energy.

Detailed explanation-3: -The Sun releases a stream of charged particles called the solar wind. On the Earth’s surface, we are protected from this barrage by the magnetosphere – a bubble created by the Earth’s magnetic field. When the solar wind hits the magnetosphere, waves of energy are transferred along the boundary between the two.

Detailed explanation-4: -In a sense, yes. The Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface.

Detailed explanation-5: -The magnetosphere is the region of space surrounding Earth where the dominant magnetic field is the magnetic field of Earth, rather than the magnetic field of interplanetary space. The magnetosphere is formed by the interaction of the solar wind with Earth’s magnetic field.

Detailed explanation-6: -Earth’s magnetic shield protects us from the cosmic radiation and is strongest at the equator and weakest near the poles. The magnetic shield diverts most of the radiation around the earth. Earth’s atmosphere shields us from most of the remaining radiation that travels to Earth.

Detailed explanation-7: -So, to answer the question, there are actually two magnetic fields that protect the earth from solar radiation: the earth’s magnetic field and the heliospheric magnetic field, which is the magnetic field carried by the solar wind itself.
