In the fltrx araaplification cornp?rct tortrs experiraaent, the bias flux penetrartes the wall of theflux co?'tserver lcecause it has been sxvitched on 21 stritably long tiuaae jcrior to the pr'oduction ofa seed spherouauak. The rrnagnetohydrodytaaztaic eqtrilibritrrn configtrrations with a non-constantX(: p.0j-B/l,B?') profile of' a helicity-driven spherornak incorporating the situation of the bias-fltrx leakage ottt of the flux conserver are ntzraaerically determined by using the novel couaabinationof the finite dif[erezace and the botundary eleraaent taaethod. Here p.c), j azud B are the pernaeabilityof VICLILIIII, the ctrrrent density and the taa?rgnetic field, respectively. The resttlts of cotmputationsshoxv that the effects of the bias-fltrx leakage cattse 21 slight rise of' the entire saf'ety factor q in thecase of #C /#P : 0.4 (#0and #P denote the total ctrrrent of coil and plasnaa, respectively) becauseof the decrease in poloidal field over ?tll space. Then, they also give rise to a 22.O'A decrease inthe nuagnetic fltrx inside the separatrix.
