1. A metal property measurement system comprising:
a metal measuring unit including a magnetic resonance sensor for detecting an electrode measuring impedance by applying a received multi-frequency current for inducing multi-frequency mutual interference to a same position of a specimen made of a metal material; and
a metal analyzing unit including a signal processor transmitting a signal for magnetic resonance to the magnetic resonance sensor and receiving an impedance measurement value, analyzing physical property information of the specimen using the impedance measured by the metal measuring unit,
wherein the metal analyzing unit includes a frequency selecting unit that receives basic information of the specimen according to a preset format and selects one or more frequencies to be applied by the metal measuring unit, and
wherein the metal analyzing unit inputs the multi-frequency, which is a plurality of frequencies selected by the frequency selection unit, to the metal measurement unit, and the electrode applies current corresponding to the input multi-frequency to the same position of the specimen, one frequency at a time, measures the impedance reflected at each frequency, and performs tomography analysis of the specimen based on the analysis of the measured impedance,
wherein the metal measuring unit is configured to include magnetic sensor measuring a magnetic field flowing through the specimen in response to the multi-frequency current applied to the same position of the specimen using the multi-frequency mutual interference, and
wherein the metal analyzing unit corrects an error of the impedance using the magnetic field information measured by the magnetic sensor.
