A system and method for authenticating a physical object. The method may include the steps of: (1) encoding a feed material with randomized information; (2) forming the object with the feed material such that one or more portions of the object have respective randomized signatures based upon at least some of the randomized information of the feed material; (3) reading the respective randomized signatures at the one or portions of the object; (4) creating a profile of the respective randomized signatures at the one or more portions of the object based upon information from the reading; (5) transporting the physical object to an authenticator, and transmitting the profile to the authenticator; (6) reading the respective randomized signatures at the one or more portions of the object by the authenticator; and (7) comparing the reading by the authenticator to the profile received by the authenticator to thereby authenticate the physical object.

Disclosed is a method for producing a soft magnetic formed part, in which, according to the first aspect, magnetically conductive particles are melted such that electrical insulating locations are arranged locally in the interspaces interrupting eddy currents which arise when the formed part is used in a magnetic field. According to a second aspect, layers are formed from the particles in the presence of an additive, the layers are locally heated by an energy supply, or a blank is formed from the particles and the additive, the blank being heated by an energy supply. The energy supply is temporally concentrated such that the magnetically conductive particles at least surface-fuse and form a structure with interspaces, in which electrical insulating locations are formed on the basis of the additive.
