| Abstract: | This paper discusses the magnetic effect of solar active cycle within Chinese territory. The data,consist of the measurements of geomagnetic north components from five geomagnetic stations during 1961-1971,and the residual error（ΔX） of quadratic expressions of secular variation are used. The results show that the variations of ΔX in each station are correlated with the sunspot numbers with period of about 11 years.The correlation coefficient was -0.77; the amplitude decreased with the latitude and the phase fall behind one year. These seem to characterize the effect of magnetic ring current of solar active cycle on the area of medium and low latitudes. |
