1. 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.
