Claim 8:
9. The electronic device of claim 7, wherein:
the electronic component comprises a plurality of electronic components each mounted on the PCB and each having at least one electrically conductive loop or winding disposed around the electronic component; and
the electronic controller is configured to, for each of the electronic components:
determine an orientation of the electronic component with respect to the direction of the ambient magnetic field from the ambient magnetic field measurement signal received from the magnetic field sensor;
determine at least one magnetic field shim current for the electronic component based on the determined orientation of the electronic component with respect to the direction of the ambient magnetic field, and a calibration table for the electronic component which maps various orientations of the electronic component with respect to the direction of the ambient magnetic field, to corresponding magnetic field shim currents; and
energize the at least one electrically conductive loop or winding of each electronic component of the plurality of electronic components to flow the determined at least one magnetic field shim current for that electronic component.
