在磁异常处理及解释推断时，常常需要确定磁化强度方向。因为只有磁化强度方向已知时，才能正确地将磁异常化到垂直磁化，简化磁异常的解释；才能可靠地进行正演计算，为求得剩余异常创造条件；为选择法解释时所需磁化强度方向提供初始值。在有些情况下，可为分辨剩磁和感磁方向是否一致的问题提
In magnetic anomaly processing and interpretation inference, it is often necessary to determine the direction of magnetization. Because only when the direction of magnetization is known, the magnetic anomaly can be properly normalized to the vertical magnetization to simplify the interpretation of the magnetic anomaly; the forward calculation can be reliably performed to create the conditions for finding the remaining anomalies; and the magnetization required for the selection method The intensity direction provides the initial value. In some cases, the problem of resolving the problem of whether the residual magnetization and the magnetic induction direction are the same can be mentioned
