Bias field generation for a magneto sensor
First Claim
Patent Images
1. A device comprising:
- a bias field generator to provide a magnetic bias field for a magnetic sensor, wherein the bias field generator is configured to provide in a first direction a magnetic field component to bias the sensor, wherein the bias field generator comprises;
a body with a cavity, the body comprising magnetic or magnetizable material, the cavity extending in the first direction and lateral to the first direction such that the cavity is laterally bounded by material of the body at least in a second direction and a third direction, the second direction being orthogonal to the first direction and the third direction being orthogonal to the second direction and the first direction, wherein the body comprises at least four inclined surfaces formed by the cavity.
