1. A method for assembling a magnetic inductor for an electromagnetic pump comprising the following steps:
providing a plurality of identical magnetic plates, each of the magnetic plates extending along a main axis and having a cross section in the shape of an involute of a circle,
assembling the plurality of magnetic plates by interlocking the magnetic plates together in order to form a tubular axial inductor core, the circle of the involute of a circle of the magnetic plates being merged together,
cutting at least one elementary coil footprint in a longitudinal surface of the tubular inductor core selected from an internal longitudinal surface and an external longitudinal surface in order to form at least one housing for an elementary coil,
providing and placing an elementary coil in each housing formed during the cutting step in order to form the magnetic inductor;
wherein between the step of cutting at least one elementary coil footprint and the step of providing and placing an elementary coil, a step of applying an insulating coating on at least part of the surface of the at least one housing formed during cutting, is further provided.
