<p>#CMT# #/CMT# The generator (20) has a set of coils (22, 23, 26-29) that is rolled around a set of axes (X, Y, Z). A set of orthogonal axes is provided for the set of coils in a common point corresponding to a central point. A set of printed circuit boards (PCBs) (32, 32, 36-39) is provided with electric tracks forming the set of coils. Each PCB includes rigid supports (42, 43, 46-49) for forming a support for the electric tracks. A plate is arranged corresponding to intensity of magnetic field generated by the coils at the central point when coils are crossed by same amount of current. #CMT# : #/CMT# An independent claim is also included for a magnetic field sensor. #CMT#USE : #/CMT# Generator for use in a magnetic field sensor (claimed) for generating a homogeneous magnetic field. #CMT#ADVANTAGE : #/CMT# The plate is arranged corresponding to the intensity of magnetic field generated by the coils at the central point when coils are crossed by same amount of current, thus allowing to manufacture the generator in a simple manner. The coils are wound on each of the axes, thus increasing homogeneity of generated magnetic field. The generator is compact. The number of printed circuit boards is limited, thus simplifying manufacturing cost of the sensor. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a generator for use in a magnetic field sensor.
