GEOLOGY

Detailed explanation-1: -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-2: -Unlike Mercury, Venus, and Mars, Earth is surrounded by an immense magnetic field called the magnetosphere.

Detailed explanation-3: -Field characteristics The average magnetic field strength in the Earth’s outer core was measured to be 25 Gauss, 50 times stronger than the magnetic field at the surface. The field is similar to that of a bar magnet. The Earth’s magnetic field is mostly caused by electric currents in the liquid outer core.

Detailed explanation-4: -Answer: No! The magnitude of the Earth’s magnetic field at its surface ranges from 25 to 65 T (0.25 to 0.65 Gauss).

Detailed explanation-5: -On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet. The magnetic field is extremely important to sustaining life on Earth.
