Abstract
The paper presents a test stand that will be used in study of Giant Magneto-Impedance (GMI) effect. Measuring system is based on primary electric law and basic instruments used in electrical metrology. GMI phenomena occurs when a magnetic material is subjected to a DC axial magnetic field and a high frequency AC current. It results in large impedance changes (up to 300%) depending on the value of magnetic field. GMI effect sensors are widely used in weak magnetic field detection. Results of the first experiment that proves proper operation of the test stand are presented. Construction of a test bench is the first step to perform extensive study on this promising technology.
