The work proposes a method allowing to check whether the desired accuracy of magnetic flux-density vector’s measurement can be achieved using a magnetic 3D probe based on three sensors with output characteristics dependent on all the magnetic-flux density vector’s components and the squared components. As the result of the method we’ve obtained analytical formulas that allow to predict the 3D-probe’s applicability for measuring the magnetic field’s magnitude with the acceptable inaccuracy.
