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.

ViviThe outer core of the Earth, composed mostly of molten iron and nickel, generates the Earth's magnetic field through a process known as the geodynamo. The movement of the conductive materials in the outer core, driven by heat and rotation, creates electrical currents that produce the magnetic field.
the layer of the earth resposible for the earths magnetic field is the core which consists of the liquid core/outer core and the solid core/inner core. The outer core constitutes mainly of nickel, colbalt and iron. in the ouer core there are convectional currents and from physics we have that when a magnetic conductor is subjected to a veloctiy a voltage is created and this voltage leads to an electric current and this leads to a magnetic charge being generated. this leads to magnetism of 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 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?
Earth's magnetic field acts as a shield, deflecting harmful solar wind and cosmic rays that could damage our atmosphere and harm living organisms. It also helps animals navigate long distances by providing a sense of direction based on the field's polarity. Additionally, the magnetic field protects our technology by reducing the impact of solar storms on satellites and power grids.
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.
