1. A magnet core produced from a composite of a powder of amorphous or nanocrystalline particles and from at least one pressing additive,wherein the particles comprise a first surface that formed a surface of the strip from which the particle was produced, and a second surface that did not form a surface of the strip, but was produced in a pulverisation process that formed the particles from the strip,wherein the overwhelming majority of these second particle surfaces are smooth cut or surfaces formed by fracture without any plastic deformation, such that the proportion T of areas of plastic deformation of the second particle surfaces is 0≦
