Claim Text:
1. A sensing system, comprising: a magnetic field sensing element arrangeable in a spatial relationship with a magnetic encoder wheel comprising alternating pole magnetic domains along a circumference thereof, wherein the magnetic encoder wheel is rotatable around a first axis, the magnetic field sensing element configured to sense magnetic field components extending generally in a direction parallel to a second axis that is perpendicular to the first axis; and a magnetic flux influencing element configured to influence magnetic field components associated with the alternating pole magnetic domains of the magnetic encoder to reduce magnetic field components associated with the first axis, wherein the magnetic flux influencing element comprises a structure comprising a ferrous path configured to redirect magnetic fields to decrease components of magnetic fields associated with a direction that is parallel with the first axis and concurrently increase components of the magnetic fields in a direction that is parallel with the second axis.
