Analisis Sensitivitas Sistem Sensor Magneto Impedance Dengan Metode Joule Heating Berbahan Vitrovac 6025z

---

Magneto impedance is a promising candidate for magnetic field detection and has rapidly advanced in terms of changes in electrical impedance experienced by conductors when influenced by a magnetic field. In this study, a magneto impedance sensor system was designed and applied in various fields using the joule heating method. The sensitivity of the magneto impedance sensor system reaches approximately picoTesla and generates a magnetic field of around 100 pT. The success of the sensor system design is determined by the sensor's response to a magnetic field close to the Earth's magnetic field scale (about 50 μT). The magneto impedance sensor is designed using a Vitrovac 6025Z core with a thickness of 0.04

mm and a width of 0.34 mm. The core is subjected to variations in Joule heating current, ranging from 0 mA to 540 mA. The sensor system testing is conducted at different frequencies, namely 100 kHz, 1 MHz, and 10 MHz for each current variation. The results of the magneto impedance sensor system testing include a significant external magnetic field and changes in impedance values. Shows optimal performance and approaches the Earth's magnetic field scale (about 50 μT) when using frequencies of 1 MHz and 10 MHz. The highest magneto impedance ratio for each frequency occurs with a current variation of 540 mA, each approximately 4.7% and 10.6%. The increase in magneto impedance ratio is directly proportional to the sensor system's sensitivity.
