STUDY OF LONG -TERM VARIATION OF COSMIC RAY INTENSITY WITH INTERPLANETARY MAGNETIC FIELD (IMF)

In present work deals the associations of interplanetary magnetic field (B) with annual mean of cosmic ray intensity for the climax (R 3.00 GV) neutron monitor, in a long period, during 1986 to 2009, which cover solar cycle 22 & 23. It is found that the value of interplanetary magnetic field shows the decreasing trend with cosmic ray intensity (CRI) & also found that, the correlation coefficient is higher during solar cycle 22 comparison to solar cycle 23. During the minimum phase of solar cycle, interplanetary magnetic field is higher & show controversial results for previous solar cycle
