| Abstract: | The reseach studies the magnetization measurement of magnetic nanoparticles by using three terminal fluxgate sensor for measuring weak magnetic signal of low frequency and designing a measurement circuit based on second harmonic method. Finally through experiment and statistic analysis, we prove that measurement system can be used to measure the mass of magnetic nanoparticles. |
