Abstract
A method for measuring the intensity of a current, comprising the steps of obtaining a computation matrix M comprising a set of terms, proportional to a distance between a measuring point and a reference point, raised to a power higher than or equal to zero, forming a vector B including measurements of the value of the magnetic field in a direction at a measuring point, computing the components of a vector A, each component being a coefficient of a decomposition of the magnetic field into spatial harmonics proportional to the intensity of the current such that the matrix relation B=M×A is satisfied, and determining the intensity.
