Abrasive article, abrasive system and method for using and forming same

An abrasive article comprising:

• a body comprising a portion comprising a metal or metal alloy;
• and
• an electronic assembly coupled to the body, wherein the electronic assembly comprises:
• an electronic device;
• a first portion underlying at least a portion of the electronic device, wherein the first portion is disposed between the body and the electronic device, and wherein the first portion comprises a material having a first average relative magnetic permeability;
• a second portion overlying at least a portion of the electronic device and comprising a material having a second average relative magnetic permeability;
• a dielectric difference value (ΔDV=DV1/DV2) of at least 1.1 and not greater than 1000, wherein DV1 is a first average dielectric value of the first portion and DV2 is a second average dielectric value of the second portion;
• and
• a magnetic permeability difference value (ΔMP=MP2/MP1) within a range of at least 1.1 and not greater than 100, wherein MP1 is the first average relative magnetic permeability and MP2 is the second average relative magnetic permeability,
• wherein the first portion comprises the first average relative magnetic permeability within a range of at least 1 and not greater than 15 for electromagnetic radiation of at least 3 kHz and not greater than 300 GHz;
• or the first average dielectric value of at least 1 and not greater than 20;
• wherein second portion comprises the second average relative magnetic permeability within a range of at least 1 and not greater than 15 for electromagnetic radiation of at least 3 kHz and not greater than 300 GHz;
• or the second average dielectric value of at least 1 and not greater than 20.
