Devices and method for determining a magnetic field

A method and device for determining values of a magnetic field component of a magnetic vector field. A method for determining values of a magnetic field component of a magnetic vector field, comprising: - determining first distribution data comprising values of the magnetic field component, for a first predetermined area defined along a predetermined surface; - determining second distribution data comprising second values of the component of the magnetic field for a second predetermined area defined along a second predetermined surface, wherein the first and the second predetermined surfaces are parallel; wherein determining second distribution data comprises manipulation of the first distribution data based on making use of intrinsic physical properties of the magnetic field; and associated device. 种用于确定磁向量场的磁场分量的值的方法，包括：对于沿预定表面定义的第预定区域，确定包括所述磁场分量的值的第分布数据；对于沿第二预定表面定义的第二预定区域，确定包括磁场的分量的第二值的第二分布数据，其中第和第二预定表面是平行的；其中确定第二分布数据包括基于利用磁场的固有物理属性来操纵第分布数据；以及相关联的设备。
