1. An electromagnetic apparatus (EMA) for measuring at least one electromagnetic property of an electrical conductor, the EMA comprising:
a plurality of electromagnetic sensors (EMSs) disposed in an array along a length, or both the length and a width of the EMA, and
circuitry comprising a microprocessor, communication circuitry, and power circuitry, wherein the circuitry is in electrical communication with the EMSs,
wherein the EMA is configured for association with the electrical conductor such that at least two EMSs are offset along the length of the electrical conductor, and
wherein the EMA comprises a guide path disposed along the length of the EMA, wherein the guide path is configured for guiding the electrical conductor along the length of the EMA, and wherein the plurality of EMSs are disposed adjacent to or within the guide path along the length of the EMA.
