Abstract
A magnetic field sensor including a body including a magnetic mechanism capable of forming a torque applied on the body by action of an external magnetic field to be detected; a connector, separated from the body, mechanically connecting the body to an inlay portion of the sensor by at least one pivot link having an axis perpendicular to the direction of the magnetic field to be detected; a detector detecting stress applied by the body by action of the torque, separated from the connector and including at least one suspended stress gauge including a first part mechanically connected to the inlay portion, a second part mechanically connected to the body, and a third part provided between the first and second parts and suspended between the inlay portion and the body.
