The dynamo effect is a geophysical theory that explains the origin of the Earth's main magnetic field in terms of a self-exciting (or self-sustaining) dynamo. In this dynamo mechanism, fluid motion in the Earth's outer core moves conducting material (liquid iron) across an already existing, weak magnetic field and generates an electric current. (Heat from radioactive decay in the core is thought to induce the convective motion.) The electric current, in turn, produces a magnetic field that also interacts with the fluid motion to create a secondary magnetic field. Together, the two fields are stronger than the original and lie essentially along the axis of the Earth's rotation.
Walter M. Elsasser, considered a "father" of the presently accepted dynamo theory as an explanation of the Earth's magnetism, proposed that this magnetic field resulted from electric currents induced in the fluid outer core of the Earth.

___________
William Gilbert published the Magnets in 1600, he concluded that the Earth is magnetic and is proposed first
Principles for the origin of this magnetism: permanent magnetism such as Landstone found in 1919, Joseph
Laramor proposed that a dynamo field could arise.
However, even after upgrading its theory,
Some major scientists improve alternative principles. Einstein believed that there might be an inequality in between
In charge of electron and proton so that earth's magnetic fields will be produced by the whole earth.
Nobel laureate Patrick Blacket used many experiments in search of a fundamental relationship between the armpits.
Speed and magnetic moment, but no one found.
