The Earth's magnetic field is the result of electric currents in the liquid metal outer core.
The outer core of the Earth is over 2,000 km thick. It sits above the solid inner core and is composed of highly conducting liquid iron and nickel. Above the outer core is the Earth's mantle.
The geodynamo is the mechanism thought to be responsible for the electric current in the core and the generation of the Earth's magnetic field through the convection of conducting fluids in the Earth's core. Other planets with a molten metal core can also have a magnetic field.

What else can I help you with?
What layer produces a magnetic field around the earth?
The outer core of the Earth, composed mainly of molten iron and nickel, produces the magnetic field that surrounds the Earth. The movement of this liquid metal creates electric currents, generating the planet's magnetic field.
What layer of the atmosphere acts like a magnet and what does it attract?
The ionosphere, a layer in the Earth's atmosphere, acts like a magnet by attracting charged particles such as electrons and ions. These charged particles are mainly attracted by the Earth's magnetic field, causing them to be trapped and move along the magnetic field lines in the ionosphere.
Which layer acts like a giant magnet why does it attract?
The outer core of the Earth acts like a giant magnet due to the movement of molten iron within it. This movement generates a magnetic field through a process called the geodynamo effect, creating the Earth's magnetic field.
How does Earth's magnetic field benefit to life?
For the planet : none. For the planet as we know it: it shields us from the solar wind, a flow of high energy particles that the sun emits (solar flares,ect.) ,much as the ozone layer protects us from ultraviolet radiation.
Which layer do scientists believe is most likely made of solid metals?
Scientists believe that the Earth's inner core is most likely made of solid metals, primarily iron and nickel. This is supported by seismic wave data and studies on the Earth's magnetic field.
In what layer is earths magnetic field produced?
Earth's magnetic field is primarily generated in the outer core layer of the planet. It is believed that the convection of molten iron and nickel within this layer, combined with the Earth's rotation, creates a dynamo effect that generates the magnetic field.
What is Earth's magnetic field created in which layer?
Earth's magnetic field is primarily generated in the outer core, which is composed of molten iron and nickel. The flow of this liquid metal creates electric currents, which in turn produce the Earth's magnetic field.
What layer generates earths magnetic field?
The Earth's magnetic field is generated by the movement of molten iron in the outer core. The flow of this liquid metal creates electric currents, which in turn generate the magnetic field surrounding the Earth.
What layer produces a magnetic field around the earth?
The outer core of the Earth, composed mainly of molten iron and nickel, produces the magnetic field that surrounds the Earth. The movement of this liquid metal creates electric currents, generating the planet's magnetic field.
What is the layer inside the Earth that creates the Earth's magnetosphere called?
The layer inside the Earth that creates the Earth's magnetosphere is called the outer core. This layer is composed of liquid iron and nickel that generates the magnetic field through the movement of its electrically conductive materials.
What layer in the earth is the magnetic field produced?
The Earth's magnetic field is primarily generated in the outer core, which is composed of molten iron and nickel. The movement of this liquid metal creates electric currents that generate the magnetic field.
What is the layer of the earth that influences earths magnetic field?
The outer core of the Earth is responsible for generating the planet's magnetic field through the motion of molten iron and nickel. This movement creates electric currents, which in turn produce the magnetic field that extends around the Earth.
The dynamo theory states that Earth's magnetic field is created in the layer known as the?
outer core of the Earth. The movement of molten iron and nickel creates electric currents that generate the magnetic field.
What layer of the earth produces its magnetic filed?
The outer core of the Earth, which is composed of molten iron and nickel, creates the planet's magnetic field. As the Earth rotates, the movement of this liquid outer core generates electric currents, which in turn produce the magnetic field.
Which layer of Earth causes Earth to act like a giant magnet?
The outer core layer of the Earth, which is made of molten iron and nickel, is responsible for generating the planet's magnetic field. The movement of the liquid outer core creates electrical currents that produce the magnetic field around Earth.
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
What is the layer of the earth with the magnetic field?
The layer of the Earth with the magnetic field is the outer core. This layer consists of molten iron and nickel that generates the planet's magnetic field through a process called the geodynamo effect.
