An electromagnetic induction device comprising a closed magnetic circuit, without air gap, of which at least one first part extends longitudinally along a longitudinal axis, the longitudinal axis being substantially rectilinear, the closed magnetic circuit being surrounded by a sleeve, said sleeve being surrounded by an electrical conductor which comprises at least one metal sheet electrically insulated on at least one of its faces, wherein:
- said at least one first part of said magnetic circuit has a section of circular form,
- said magnetic circuit is layered by several layers of magnetic material separated by an electrical insulation,
- said sleeve comprises an inner face comprising a circular section closely fitting the form of said magnetic circuit, and an outer face comprising curved parts and planar parts, and
- said sleeve comprises a plurality of parts adapted to cooperate to surround said magnetic circuit.
