Relationship between the solar wind-magnetosphere energy coupling function and the energy consumption in the magnetospheric system is tested by the samples during period of northward Bz(>10 nT) of IMF. It is shown that the energy function which can well describe the solar wind-magnetosphere coupling when Bz>0 is no more applicable for Bz>10 nT, but the coupling still exists, the effects of which are mainly found at the polar cap. Dst often turns to positive when Bz> 10 nT and the coupling mechanism is different from that when Bz<0. New coupling function has to be introduced to describe the solar wind-magnetosphere coupling for the case of Bz> 10 nT.
