What are outer cores prpopertys?
its responsible for Earth's magnetic field.
Is mafic rocks in the mantle earths magntic field?
No. The Earth's magnetic field consists of invisible lines of force, not rock. The mangetic fiild itself is driven by currents in the outer core, which is made of molten iron and nickel.
Is the Earth's magnetic field produced by a large bar magnet inside the planet?
No. The magnetic field is produced by currents in Earth's outer core, which is composed largely of molten iron.
What in the earth's interior allows us to use a compass?
The Earth has a magnetic iron core.Actually, it isn't a magnetic 'core'. It is a magnetic deposit that is in the outer 20% of the earths mass. It is like a bubble of cherry juice under the crust of a pie baking. It moves around and slightly changes position over the years, but cycles back to it's prior position on a regular schedule. That is why magnetic north constantly moves back and forth. If you look at the 'magnetic declination', you will see how it changes from year to year. The Magnetic North Pole is actually some distance form the geographic north pole, north of the Hudson Bay. And by the way, the magnetic north pole is actually magnetically the south pole. If you have a magnet that is marked 'N' and 'S', suspend it from a string or place it in a floating saucer. The 'N' will point to the north, being attracted to the SOUTH (opposites attract) magnetic pole of the earth. Somewhere, this got reversed and no one wants to correct it.(response) Allow me to quote from wikipedia: The Earth's magnetic field is mostly caused by electric currents in the liquid outer core. So, although it is the outer core, it is still the core. Not the outer 20% of the Earth's mass. Bear in mind, it is the core that is composed of highly conductive nickel and iron. The layer of magma in the mantle is not electrically conductive, therefore it would not support currents that could generate a magnetic field."mostly caused by electric currents in the liquid outer core" The liquid outer core as defined can be and probably is within the outer 20% of the earth's mass. "Inthe outer 20%" does not mean "is the outer 20%". The specific highly magnetic deposit that defines the earths magnetic field can be and is influenced by electrical current within the core or outer core as you wish. The magnetic deposit may not be totally magnetic on its own. Even as a nail in proximity of a pulsing electric current is not initially magnetic, it will become magnetised by the current, and eventually become magnetic because of the realignment of molecules within it. So yes, the current in the outer core causes or influences but is not the primary source of the earth's magnetic field.
Liquid iron-nickel alloy that generates Earth's magnetic field?
the outer core of the earth
Does plate tectonics produce earths magnetic field?
No. Earth's magnetic field is produced by currents in the liquid outer core.
What is made of liquid iron and nickel moves to produce earths magnetic field?
The Outer Core has magnetic field and it is made out of iron and nickel
What happens in earth interior to produce earths magnetic field describe the layer where the magnetic field is produced?
What escapes the crust is what we observe as the earths magnetic field. The outer core is a rotating mass of fluid metal that induces an electrical current which in turn generates the magnetosphere.
The convention that causes earths magnetic field happens in earths?
core
What is made of solid iron and nickel spins to produce earths magnetic field?
Earth's outer core (as opposed to the inner core).
Earth's magnetic field results from the spinning of the?
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
What happens in the Earth's interior to produce Earth's magnetic field describe to layer where the magnetic field is produced?
What escapes the crust is what we observe as the earths magnetic field. The outer core is a rotating mass of fluid metal that induces an electrical current which in turn generates the magnetosphere.
Where does the convection that causes earths magnetic field?
The convection that causes Earth's magnetic field happens in Earth's molten outer core.
The dynamo theory states that earths magnetic field is created in layers?
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.
What creates the Earths magnetic field?
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
What do geologists think creates earths magnetic field?
Electric currents in Earth's molten outer core.
What causes the earths magnatic field?
The earth's magnetic field is caused by the circulating magma of the outer core going around the solid iron inner core.
