    "Magneto Impedance, as a promising alternative in detecting magnetic fields, has undergone rapid development in altering the electrical impedance experienced by conductors when exposed to magnetic fields. This research involves the design and implementation of a magneto impedance sensor system utilizing the Joule heating method. The sensitivity of this magneto impedance sensor system reaches approximately picoTesla, generating magnetic fields of around 100 pT. The success of the sensor system's design is evaluated based on its response to magnetic fields approaching the Earth's magnetic field scale, approximately 50 μT. This magneto impedance sensor is crafted using a core made of Vitrovac 6025Z, with a thickness of 0.04 mm and a width of 0.34 mm. The sensor's core experiences 6 varying Joule heating currents, ranging from 0 mA to 540 mA. The sensor system is subjected to testing at frequencies 100 kHz for each current variation. The magneto impedance sensor system generates output in the form of impedance and magnetic fields. The output values will be used to determine the magneto impedance ratio.
