Embodiments relate to magnetic field current sensors having sensor elements for sensing at least two magnetic field components, for example Bx and By. The current in a conductor is estimated by Bx and Bx/By, wherein Bx is the primary measurement and Bx/By is a corrective term used to account for position tolerances between the sensor and the conductor. In other embodiments, the corrective term can be dBx/By, where dBx is a difference in between components sensed at different sensor elements. The particular field components can vary in embodiments; for example, the current can be estimated by By and By/Bx, or dBy/Bx or some other arrangement.
