Claim 0:
1. A system for sorting metallic objects by magnetic separation, comprising:
an electromagnetic core comprising:
at least a first portion including a winding,
a second portion, the second portion being wider than the first portion, and
a bottom connecting the first portion to the second portion,

a sorting flap arranged facing said electromagnetic core to provide, between the sorting flap and the electromagnetic core, a circulation space for a conveyor of objects to be sorted from the first portion toward the second portion, wherein the sorting flap comprises a magnetic element arranged to form an air gap between the first portion and the sorting flap, said air gap forming a magnetic barrier opposing passage of non-magnetic metallic objects, such that said non-magnetic metallic objects are ejected from the conveyor,
the second portion being arranged between the bottom and a portion of the magnetic elements of the sorting flap opposite the air gap to ensure a return of the magnetic flux lines toward the first portion.
