Write a note on Earth’s magnetism.
A is a pair of poles separated by a . The north and south poles are separated by certain distances, makes it a dipole.
The within the Earth's core has a pole near the pole and vice-versa.
An imaginary line called the magnetic axis connects these two magnetic poles.
The axis bisects the geographic north pole at the pole, also known as the pole, and geographic south pole at the pole, also known as the pole.
The magnetic and the geographical axis or the never coincide with each other.
The of Earth's magnetic axis is about degrees with the of the Earth.
Some significant factors that causes the Earth's magnetism are the in the Earth's masses, and .
The magnetic field of Earth is generated by a within the Earth's crust or surface.
Earth's core has a radius of around compared to the Earth's radius of \(6400\ km\).
