A magnetising device in a web processing machine for magnetising a magnetisable area of a web of packaging material, said magnetising device comprising:
- a first magnetic component having a north pole and a south pole, and
- a second magnetic component having a north pole and a south pole,
- wherein poles of a first and same polarity are arranged adjacent in an opposed relationship, and
- wherein poles of a second and same polarity are arranged remote from each other.
A packaging material comprising a plurality of magnetisable portions thereon comprising at least one spot per package to be formed from the packaging material, wherein at least one of the magnetisable portions provides a first magnetic mark carrying a magnetic field pattern and wherein the magnetic pattern of the first magnetic mark is represents data or a position on the packaging material, wherein the magnetic field pattern comprises a first magnetic component having a north pole and a south pole, and a second magnetic component having a north pole and a south pole, wherein poles of a first and same polarity are arranged adjacent in an opposed relationship and wherein poles of a second and the same polarity are arranged remote from each other.
