A wire spool for remaining wire recognition for wire (1) with a leading
wire end (4) and a trailing wire end (2), which is wound on the spool
body (30, 40) in N windings, whereby the spool body (30, 40) has
side walls (40) on both sides and a spool drum (30), with a magnet
(10) that is fastened in the spool body (30, 40), whereby the installation
position of the magnet (10) in the spool body (30, 40) is such that
the magnetic field lines (11, 12) are arranged along the magnet (10)
essentially parallel to the winding direction of the wire (1) on the spool
drum (30).
