Abstract:
1. A magnetic field sensor calibratable during measurement operation for detecting first, second, and third spatial components B z B y and B x of a magnetic field at a reference point, wherein the magnetic field comprises at least one of measurement field components and calibration field components, wherein the measurement field components comprise first, second, and third measurement field components B Mz , B My and B Mx , and wherein the calibration field components comprise first, second, and third calibration field components B Kz , B Ky and B Kx , comprising: a first sensor element arrangement for detecting the first magnetic field component B a second sensor element arrangement for detecting the second magnetic field component B a third sensor element arrangement for detecting the third magnetic field component B an excitation line arranged such with respect to the first, second, and third sensor element arrangements that when impressing a predetermined current into the excitation line, a first predetermined calibration field component B
