Magnetic-field-measuring probe

A device for analyzing an electrical current during operation, comprising:

• at least one probe (12) for measuring a magnetic field comprising at least two magnetoresistive or magnetoinductive sensors (14, 16) which are sensitive to the magnetic field along a selected measurement axis, said two magnetoresistive or magnetoinductive sensors (14, 16) being rigidly connected to each other in a position such that their selected measurement axes are parallel and offset relative to each other in a transverse direction relative to their selected measurement axes, the probe comprising output terminals which are specific to each magnetoresistive or magnetoinductive sensor in order to provide a signal which is representative of the magnetic field measured by each sensor along the selected measurement axis thereof;
• a processing chain (20, 22) which is specific to each magnetoresistive or magnetoinductive sensor (14, 16);
• means (24, 26) for processing the signals from the various processing chains, which processing means comprising means for evaluating a difference between the field values measured by two magnetoresistive or magnetoinductive sensors having selected measurement axes which are parallel and which are offset transversely relative to each other;
• and
• means for evaluating a ratio between said difference and a distance separating the two magnetoresistive or magnetoinductive sensors.
