How is the earth's magnetic field created?

Answer 1

A few % of the magnetic field comes from the stream of charged particles coming from the Sun. This is why the magnetic field varies greatly in Polar Regions during a sunspot storm.

The majority of the field is generated deep inside the Earth by electrical currents in the liquid part of the outer core. The nett result of these currents generates a magnetic field.

The Curie Temperature of magnetic materials ensures that there are no magnetic materials deep in the Earth.

Answer 2

The earth's magnetic field is caused by the fact that the earth has a moltern iron core. When moltern iron spins it causes an electric field. This causes an electromagnetic field. Some planets are too large or too small for the iron in their core to be molten.

Answer 3

The Earth's magnetic field is created by the movement of molten iron and nickel in the outer core of the planet. The rotation of Earth creates a dynamo effect that generates electrical currents, which in turn produce the magnetic field. This magnetic field extends out into space and helps protect the Earth from harmful solar radiation.

Answer 4

The magnetic field of the Earth is formed by the motion of the Earth's core.

Answer 5

The Earths magnetic field originates from the Core in the centreof the earth it is made up of Nickel and iron and is a solid.

Answer 6

Due to its revolutionary and rotatory motion.

Answer 7

The molten iron in the upper layers of the core create the magnetic field of the Earth.

Answer 8

From the massive iron core at its center!
