A method is described, which permits the measurement of magnetic field distributions in two or three dimensions. It is based on a nuclear magnetic resonance technique, the Fourier-Zeugmatography, which was recently developed for two- and three-dimensional spin density imaging. The spatial assignment of the nuclear signal is achieved without any mechanical movement by a sequence of pulsed magnetic field gradients during a series of free induction decays. An example of a two-dimensional field imaging in the gap of a conventional electromagnet is presented. The field distribution was measured with a field resolution of 1. 5 multiplied by (times) 10** minus **6 Tesla, and a spatial resolution of 0. 065 cm in a time of 9. 7 min.
