Inductive core exhibiting low magnetic losses

An inductor core for magnetic inductor, comprising:

• a body comprising a ferromagnetic material and one or more magnets, in which the one or more magnets at least partially form a first path for circulating magnetic flux lines produced by the one or more magnets such that the first path comprises at a first end a designated end south pole, and at a second end a designated end north pole, and
• wherein the ferromagnetic material at least partially forms a second path for circulating the magnetic flux lines,
• wherein the ferromagnetic material extends continuously from the south pole to the north pole along the one or more magnets, and comprising, facing the end south pole, a non-magnetic zone and, facing the end north pole, a non-magnetic zone forcing the magnetic flux lines coming out of the end north pole to take the second path and to loop back on the end south pole, the non-magnetic zones being designated end non-magnetic zones, such that a transversal section of the inductor core, perpendicular to the flux lines, comprises both the first path for circulating and the second path for circulating,
• wherein each of the one or more magnets is disposed in a cavity of the body such that a lateral face of each magnet is at least partly surrounded by ferromagnetic material of the body.
