Abstract: A magnetic head for a magnetic detector for detecting metal particles in a hydraulic circuit includes an axial body internally including at least one magnet, at least a first electrode defining an air gap zone located in the magnetic field created by the magnet, such that the circuit creates a particle alignment zone in the air gap, and an electrical connector for electrically connecting the electrodes. The magnet can be a diametrically magnetized magnet.

Abstract: This magnetic head (11) for a magnetic detector for detecting metal particles in a hydraulic circuit comprises an axial body (14) internally comprising at least one magnet (15, 16), at least a first electrode (17, 18) defining an air gap (E) located in the magnetic field created by the magnet, such that the circuit creates a particle alignment zone in the air gap, and means for electrically connecting (C) the electrodes.
The magnet is a diametrically magnetized magnet.
