The inner core and outer core of the planet are composed primarily of iron and nickel. The outer core is liquid and the inner core is solid. It is thought that the convective motion of the liquid outer core is responsible for generating the main field. Recent studies indicate that the inner core of the Earth may rotate a bit faster than the outer core and it is possible that this rotation may be associated with field reversals.

What does the inner magma in the Earth do?
The inner magma in the Earth is located in the mantle and core regions. It plays a crucial role in driving plate tectonics and creating volcanic activity on the Earth's surface through processes like mantle convection and magma upwelling. This molten material also helps regulate the Earth's magnetic field.
Do swallows use the earth's magnetism to find there way to the tropics where they migrate or do they use the angle of the sun to find there way?
Swallows use both the Earth's magnetism and the angle of the sun to find their way to the tropics when they migrate. They may also use topographic features and their sense of smell to find their way to the tropics for the winter.
Heat from the earth's interior causes convection currents in which layer of earth?
Convection currents in the magma drive plate tectonics.Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere.
What is axis of polarity?
The axis of polarity refers to the imaginary line around which the Earth's magnetic field is oriented. It is not fixed and can shift over time due to geophysical processes in the Earth's core. The axis of polarity plays a key role in determining the orientation of a magnetic compass.
What causes one year?
A year is the amount of time that the earth takes to do one complete orbit of the sun. The earth is locked in to an orbit which is dependant on its speed of motion, its mass and its distance from the sun.
What is the leading theory for what causes earth's magnetic field?
The Dynamo Theory it what causes Earth's Magnetic Field
What are the lines of force around a magnet?
the imaginary lines around the magnet is a magnitic field and strong
Where does the convection that causes earths magnetic field?
The convection that causes Earth's magnetic field happens in Earth's molten outer core.
Is it true when magnitic minerals grains in a rock form they become magnetized in the direction parallel to earth existing magnetic field?
Yes, when magnetic mineral grains in a rock form, they can become magnetized in the direction parallel to Earth's existing magnetic field. This is due to the alignment of the mineral grains with the magnetic field at the time of formation, resulting in the retention of this magnetization in the rock.
How is earth a magnetic field?
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.
Does phobos have a magnitic feild?
yes
What causes Earth's magnetic field to have the shape it does?
As you might already know, a magnet is the most powerful at it's ends. So what the inner core of the Earth's magnetic field does is that it surround the Earth. Thank you.
Is aluminum magnitic?
No, iron and steel are though.
Along with the spin of the Earth what causes its magnetic field?
The Earth's magnetic field is caused by the movement of molten iron and nickel in its outer core. This creates a dynamo effect, generating electric currents that produce the magnetic field.
What causes arnie to be lighter on venus than on earth?
Venus has less mass than earth and therefore a weaker gravity field.
What is in the center of the earth's core?
Earth's inner core is made of solid iron and causes earth's magnetic field, which deflects dangerous particles shot out by our sun.
The convention that causes earths magnetic field happens in earths?
core
