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.

Learners will construct a soda bottle magnetometer collect data and analyze the results to detect magnetic storm events. 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. 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.

This page contains a brief introduction to magnetism and earth s field. Earth s force field also comes from somewhere else. Magnetic anomalies result from geologic features enhancing or depressing the local magnetic field. Earth s second magnetic field captured in satellite images.

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. This is an activity about changes in the earth s magnetic field during magnetic storms. Welcome to the image satellite tutorial on earth s magnetic field. These maps increase knowledge of subsurface structure and composition of the earth s crust.
