We have studied the configuration of the polar cusps in a static MHD equilibrium model. By introducing two quasi-linear equilibrium models, we show that one can obtain magnetospheric configurations with the magnetopause neutral points located tailward of the earth and at the same time with reasonable tail magnetic field geometry. We also conclude that by the pressure balance principle across the magnetopause, if the magnetopause is a smooth surface then the neutral points cannot be on the dayside boundary. |
