Commenswere made on he academically conrover- sial of he basic physical mechanism of LDGMI effec and gian magneo-impedance(GMI )effec . The differ- ence of he LDGMI effec and GMI effec was regarded as resuled in he differen work mode wih he same basic physical mechanism,wihin which boh had advanages and disadvanages in he applicaion develop- men ,andformed hecomplemenaryrelaionship. Becauseof advanagesof hehigher sensiiviy,higherreli- abiliy and greaer flexible,he LDGMI had played a paricular role in he developmen and applicaion of he new ypeofmagneicsensor,andanew ypeofmagneicmeasuringinsrumen . Promisingof heLDGMIeffec was suggesed which would be worhy of greaer concern in he indusry. Key words:gian magneo-impedance;longiudinally driven gian magneo-impedance;longiudinally driven gian
