Method of producing an oppositely magnetized magnetic structure

A method of producing a magnetic structure within or on a substrate material, comprising:

• producing a first number of cavities within or on the substrate material, and filling the first number of cavities with a first hard magnetic material exhibiting a first coercive field strength so as to generate a first hard magnetic arrangement;
• producing a second number of cavities within or on the substrate material, and filling the second number of cavities with a second hard magnetic material exhibiting a second coercive field strength, which is smaller than the first coercive field strength, so as to create a second hard magnetic arrangement;
• magnetizing the first and second hard magnetic arrangements in a first direction by means of a first magnetic field exhibiting a first magnetic field strength which exceeds the first and second coercive field strengths;
• and
• magnetizing the second hard magnetic arrangement in a second direction different from the first direction by means of a second magnetic field exhibiting a second magnetic field strength which falls below the first coercive field strength but exceeds the second coercive field strength,
• wherein said magnetization of the second hard magnetic arrangement comprises exposing the first and second hard magnetic arrangements to the second magnetic field.
