Diagram Of Earth S Magnetic Field
Earth s magnetic field also known as the geomagnetic field is the magnetic field that extends from the earth s interior out into space where it interacts with the solar wind a stream of charged particles emanating from the sun the magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the earth s outer core.
Diagram of earth s magnetic field. Noaa s national centers for environmental information and the collocated world data centers boulder operated by noaa nesdis ncei archive and make available geomagnetic data and information relating to earth s magnetic field and earth sun environment including current declination geomagnetic field models and magnetic indices geomagnetic observatory data and geomagnetic surveys. Earth s magnetic field is defined by the north and south poles that align generally with the axis of rotation figure 9 13. The lines of magnetic force flow into earth in the northern hemisphere and out of earth in the southern hemisphere.
The dotted lines at the centre of the diagram represent the processes in the earth s core that produce a magnetic field. Larger image earth s magnetic field comes from this ocean of iron which is an electrically conducting fluid in constant motion. Earth s magnetic field and dipole moment definition earth s magnetic field also known as the geomagnetic field is the magnetic field that extends from the earth s interior out into space where it meets the solar wind a stream of charged particles emanating from the sun.
This shield the magnetosphere is bullet shaped with a nose that lies about 64 000 kilometers just over 39 768 miles toward the sun. Sitting atop the hot inner core the liquid outer core seethes and roils like water in a pan on a hot stove. A magnetosphere is that area of space around a planet that is controlled by the planet s magnetic field.
A schematic diagram of earth s interior. Because of the shape of the field lines the magnetic force trends at different angles to the surface. The shape of the earth s magnetosphere is the direct result of being blasted by solar wind.
The arrows represent invisible lines of force known as magnetic field lines. Diagram of earth s magnetic field this diagram illustrates the solar wind flowing around and beyond earth s magnetic shield.
