Abstract
A device, an ammeter and a motor vehicle, having a first section and a second section of a conductor for the purpose of measuring the electrical amperage in the conductor are described; a first sensor means and a second sensor means being provided; the current flowing in the first section and in the second section generating a useful magnetic field; the first sensor means being provided to measure the useful magnetic field; the second sensor means being provided in a location where the useful magnetic field disappears; the second sensor means being provided to measure a magnetic interference field; and the measurement of the useful magnetic field being correctable by the measurement of the magnetic interference field.
