Abstract
A magnetic head array for use in a magnetographic printer, in which local magnetic fields are generated by U-shaped wires each having a complete magnetic yoke formed by bending a foil made up of alternative parallel conductive and soft-magnetic wires over a thin sheet of soft-magnetic material. In a magnetographic printer the array is brought into contact at the U-shape bend with a magnetizable medium. The areas magnetized by the individual wires are sharply defined.
