磁共振对磁场变化非常敏感。这种固有的灵敏度可以用来测量人体内流动的小电流。本报告描述了一个实验中，小电流施加到一个活生生的对象的前臂所产生的磁场已被检测到的组织。它显示了如何使用这种测量来测量电流密度。建议的技术是用来测量一个组件的电流密度在体外的盐溶液。
Magnetic resonance is very sensitive to magnetic field variations. This inherent sensitivity can be exploited to measure small electric currents flowing in the human body. This report describes an experiment in which the magnetic fields produced by small currents applied to the forearm of a living subject have been detected in the tissue. It shows how such measurements have been used to measure current density. The suggested technique is used to measure one component of a current density in a saline solution in vitro.
