虚拟磁位移是用来检查动物的磁感受能力，通过改变当地的磁场，以模仿一个存在于其他地方。这项技术可以用来测试动物是否使用磁图。磁图的可行性取决于动物的坐标系由哪些磁参数组成，以及它们对这些参数的敏感程度。以前的研究没有考虑到敏感性可以改变动物对虚拟磁位移位置的印象的程度。我们重新评估了所有使用虚拟磁位移的已发表研究，假设动物对磁参数的敏感性最高。绝大多数人容易受到存在替代可能的虚拟位置的影响。在某些情况下，这可能会导致结果变得模棱两可。我们提出了一个工具，可视化所有可能的虚拟磁位移替代位置（ViMDAL），并提出了如何进一步研究动物磁感受的变化进行和报告。虚拟磁位移位置可视化工具（ViMDAL）用于分析动物虚拟磁位移的现有数据。这表明存在可能混淆现有研究的替代可能的虚拟位置。
Virtual magnetic displacements are used to examine the magnetoreceptive ability of animals by changing the local magnetic field to emulate one that exists elsewhere. This technique can be used to test whether animals use a magnetic map. The viability of a magnetic map is dependant upon which magnetic parameters an animal’s coordinate system is composed of, and how sensitive they are to those parameters. Previous research has not considered the degree to which sensitivity can change an animal’s impression of where a virtual magnetic displacement is located. We re-assessed all published studies that use virtual magnetic displacements assuming the highest likely level of sensitivity to magnetic parameters in animals. The vast majority are susceptible to the existence of alternate possible virtual locations. In some cases, this can cause results to become ambiguous. We present a tool for visualising all possible virtual magnetic displacement alternative locations (ViMDAL) and propose changes to how further research on animal magnetoreception is conducted and reported. A tool for visualising virtual magnetic displacement locations (ViMDAL) is used to analyse existing data on virtual magnetic displacements in animals. This shows the existence of alternate possible virtual locations that may confound existing research.
