The dynamo theory helps explain how a planet or star can make its own magnetic field. William Gilbert was the first person to suggest that the Earth is a magnet in a report called de Magnete in 1600.

The dynamo theory explains how the Earth's magnetic field is generated by the motion of molten iron in its outer core. It suggests that the rotation of the Earth combined with convective motion in the outer core creates electrical currents that generate the magnetic field.
the two theories that attempt to explain earths magnetic field are Dynamo theory--the theory that is believed by the majority of geologists. it says the rotation of the earth causes the liquid core to move in one overall direction, causing the movement of electrical charges, creating the current making the magnetic field. Rapid-decay theory---is believed by the minority of geologists. it makes assumptions about how the earth was formed to calculate how much electrical current would be generated and how much it would have slowed down. =
Obviously Dynamo has a twin brother, no other way to explain some of his tricks. He is still the best magician ever though!
In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.

Dynamo theory is the idea that a magnetic field generator exists within the Earth's outer core. It is this generator that explains the difference between the inner and outer core.

The theory of plate tectonics helps to explain how earthquakes and volcanic eruptions occur.

the theory of evolution
Scientists think that the Earth's magnetic field is generated by movements in the liquid outer core. (exact e2020 answer help out you wiki answers shortcuts!!)if you want a more serious answer i suggest looking up the "dynamo theory"
The dynamo theory states that Earth's magnetic field is generated by the movement of molten iron in the outer core of the planet. The fluid motion of the molten iron creates electric currents, which in turn produce the magnetic field that surrounds Earth. This process operates similar to a self-sustaining dynamo, hence the name "dynamo theory."
The rapid decay theory explains the decrease in the strength of the earth's magnetic field better then the dynamo theory. Although the dynamo theory explains the explains the reversals where the field pointed in the opposite directions better. The rapid decay theory allows for it, but only if there is an event of cataclysmic volcanic and geological activity. The rapid decay theory also explains the magnetic fields on the other planets correctly.
