WebThe article describes lunar daily magnetic variation inH, D andZ components of the earth's magnetic field at Istanbul. Maximum occurs at 10.03 l.hr. (lunar hour) in theH component, 3.38 l.hr. in theD and 2.15 l.hr. in theZ component, during the period 1949 to 1968. Also, the seasonal variation of the lunar magnetic variation has been determined and it is seen … WebThe geomagnetic lunar daily variation field, L, was studied using all available results of lunar analysis of geomagnetic data from a total of 37 stations. Equivalent external (overhead) and internal (induced within the earth) electric current systems responsible for L variations with respect to dip latitude were estimated by the method of spherical … WebDiurnal Variations of the Earth's Magnetic Field. Of more importance to exploration geophysical surveys are the daily, or diurnal, variations of the Earth's magnetic field. These variations were first discovered in 1722 in England when it was also noted that these daily variations were larger in summer than in winter. The plot below shows ... the pigeon forge trolley
