The present invention relates high power AC steering flux cancelling inductors and processes of making and using same. When properly configured and wired such inductors, separate the AC component and DC component of a high power current thus allowing the smaller AC fraction of the overall current to be carried by much smaller cross-sectional litz wires. Such high power AC steering flux cancelling inductors are more efficient at avoiding core saturation compared to standard inductors, yet they are less expensive without the need for large cross-sectional litz AC carrying wires. In addition to the aforementioned benefits, such high power AC steering flux cancelling inductor permits the levels of AC and DC current to be efficiently monitored as such currents are separated.

The magnetic sensor can prevent an increase of a positional detection error of a subject/object even in the case of applying an external magnetic field with a magnetic field intensity exceeding a predetermined range. A magnetic sensor is equipped with a magnetoresistive effect element (MR element) 11 that can detect an external magnetic field and a soft magnetic body shield 12. The soft magnetic body shield(s) 12 are/is positioned above and/or below the MR element 11 in a side view, and the size of the MR element 11 is physically included within a perimeter of the soft magnetic body shield 12.
