A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to ...
by using measurements at a lower elevation and extrapolating upward, assuming
continuity. This technique is commonly used to merge different measurements to a common level so as to reduce scatter and allow for easier analysis.
