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.

Satellite images of earth s magnetic field.

Earth s second magnetic field captured in satellite images. This page contains a brief introduction to magnetism and earth s field. Welcome to the image satellite tutorial on earth s magnetic field. 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.

Magnetic anomalies result from geologic features enhancing or depressing the local magnetic field. Earth is a pretty wild place to live. 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. 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.

Learners will construct a soda bottle magnetometer collect data and analyze the results to detect magnetic storm events. Changes measured by the swarm satellite over the past 6 months shows that earth s magnetic field is changing. Earth s force field also comes from somewhere else. These maps increase knowledge of subsurface structure and composition of the earth s crust.
