摘要
Determination and calculation of magnetic parameters of rocks and minerals are faced with some problems such as ambiguous location determination,incorrect units of T0,ID confusion of specimen surface and negative magnetic susceptibility.On the basis of previous studies and starting with determination of Gauss position using mechanical magnetometer and formula derivation,this paper analyzed the cause of negative magnetic values and the measures for improvement were put forward.
