地下基础设施的定位和识别对于管理和维护城市基础设施和公用设施以及定位地下灾害至关重要。低频振荡磁场由于传播介质而受到的衰减比探地雷达小。在这里，电子齿轮，旋转钕磁铁项目振荡磁场，这是操纵，以提供对象识别从动态磁力计数据的快速分析。铁磁材料直接与旋转磁场相互作用。感应反向传播磁场的涡流在导电的非铁磁材料中产生。两个应用突出的初步实验：铜，铝和钢管之间的歧视，并提高埋爆炸装置的检测。
Location and identification of subterranean infrastructure is crucial for managing and maintaining urban infrastructure and utility, and locating subsurface hazards. Low-frequency oscillating magnetic fields suffer less attenuation due to propagating media than ground penetrating radar. Here, electronically-geared, rotating neodymium magnets project oscillating magnetic fields which are manipulated to provide object identification from rapid analysis of dynamic magnetometer data. Ferromagnetic materials interact directly with the rotating magnetic field. Eddy currents, which induce a counter-propagating magnetic field, are generated in conductive, non-ferromagnetic materials. Two applications are highlighted by preliminary experiments: discrimination between copper, aluminum and steel pipes, and improved detection of buried explosive devices.
