Abstract

Efek magnetoimpedansi pada kawat tembaga yang dideposisi dengan lapisan Ni80Fe20/Cu telah berhasil diamati. Pengukuran dilakukan pada frekuensi rendah (20 ? 100 kHz) dengan variasi jumlah lapisan Ni80Fe20/Cu. Hasil pengukuran menunjukkan rasio magnetoimpedansi meningkat secara signifikan dari 6,4% menjadi 50% dengan peningkatan jumlah lapisan dari   N = 1 hingga N = 3. Hasil pengukuran juga menunjukkan sensitifitas terhadap medan juga meningkat 20 kali lipat dengan peningkatan jumlah lapisan Ni80Fe20/Cu.

Abstract

Sensitive magnetic field sensor based on compensated double pick up coil has been developed. In order to confirm sensitifity of modified design, experiment carried out in two steps. Firstly, sensitify of conventional design is clarified. Here pick up coil as an active sensor and solenoid as an exitation coil is separately made. Secondly, modified sensor of integrated configuration is developed. Here for both active flux gate sensor and the exitation coil is made in same one core magnetic. Ferrite and standar foil soft magnetic is utilized in this experiment. In attention, frequency of 50 Hz is used for the whole experimens. A result showed that sensitvity of the integrated configuration sensor is much larger than conventional one. Then, power consume of the integrated flux gate sensor is much lower than conventional. Finally, a range measurement of the integrated configuration sensor can be realized less than 20 T which potential may perhaps sense a change of natural local magnetic field.
