A method for controlling the production of a magnet using a sensor able to emit a signal in the presence of a magnetic induction and defining a measuring axis, the magnet being a permanent magnet with symmetry of revolution relative to an axis, called mechanical axis, the magnet having a center and a maximum dimension (D max), the method comprising at least the following step: a) performing a first measurement of a component of the magnetic induction produced by the magnet using the sensor by implementing the following sub-steps: a1) relative positioning of the magnet and the sensor so that the mechanical axis of the magnet and the measuring axis of the sensor are aligned with an allowance of 5 degrees, the distance between the sensor and the center of the magnet, called first distance, being greater than or equal to three times the maximum dimension (D max) of the magnet, and a2) relative movement of the magnet and the sensor, along a direction perpendicular to the mechanical axis of the magnet, the first measurement corresponding to the maximum signal measured by the sensor during the movement, b) performing a second measurement of a component of the magnetic induction produced by the magnet using the sensor by implementing the following sub-steps: b1) positioning the sensor so that the measuring axis of the sensor is perpendicular to the mechanical axis of the magnet and is in a plane perpendicular to the mechanical axis of the magnet passing through a point of the magnet, the distance between the sensor and the center of the magnet, called second distance, being greater than or equal to three times the maximum dimension (D max) of the magnet, b2) rotating the magnet relative to the mechanical axis by at least one revolution, b3) measuring the maximum and minimum magnetic inductions during the rotation of the magnet in sub-step b2), the second measurement being obtained from maximum and minimum magnetic inductions, and c) calculating the angular deviation (a) of the equivalent magnetic moment of the magnet from the first measurement and the second measurement. a) performing a first measurement of a component of the magnetic induction produced
