Launched in november 2013 by the european space agency esa the three satellite swarm constellation is providing new insights into the workings of earth s global magnetic field.
Satellite images of earth s magnetic field.
Earth magnetic anomaly grid 2 arc minute resolution emag2 is compiled from satellite ship and airborne magnetic measurements.
It also provides links to additional image reading materials and a collection of classroom activities that help students understand earth s manetic field and its changes through time and space.
Earth is a pretty wild place to live.
Generated by the motion of molten iron in earth s core the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our.
Shades of red show areas where it is strengthening and shades of blue show areas that.
Changes measured by the swarm satellite over the past 6 months shows that earth s magnetic field is changing.
This page contains a brief introduction to magnetism and earth s field.
Earth s force field also comes from somewhere else.
Earth s second magnetic field captured in satellite images.
These maps increase knowledge of subsurface structure and composition of the earth s crust.
This is an activity about changes in the earth s magnetic field during magnetic storms.
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.
