ABSTRACT:
A method of non-invasive determination of electrical current distribution is disclosed. The method utilizes mathematical calculations on data obtained by a probe with non-uniformly wound detection coil. While non-uniform, the coil winding is specific according to a known and determined function, such as a sinusoidal variation. As a further method, the probe may rotate about an area of interest and the data then may be subjected to a Fourier analysis for further refined results. Multiple coils may be used in the probe, each with a different coil function which could include one uniform coil. Also disclosed is a method for making the coils necessary in the practice of the method.
