Abstract

Material containing magnetisable particles is passed through a unit to allow the material to be selectively magnetised. A linear arrangement has a series of permanent magnets that alternate with the pole pieces. The sheet material is passed beneath the magnet-pole pieces and strips of material corresponding to the pole pieces are magnetised. An alternative has disc shaped magnets (14) and an iron pole piece (15) that are located in a PTFE block (16). The axial magnetised disc and pole piece are shielded by plates (17) inset into the body. The head is moved across the sheet material to produce selective magnetisation.
