论文摘要
解释了具有成本效益的振动样品计的设计和制造。可以使用操作放大器电路获得检测到的信号的改进。制造的螺旋检测线圈设计增强了由于屏蔽通量而获得的感应电压。通过将低音扬声器作为执行器和有机玻璃作为振动介质，可以获得自制的设置。锁定放大器通过相检测原理分析了增强的诱导电压信号。从镍（99％纯度）样品中的扩增和非扩增信号进行了研究。通过校准结合了固定性和保留性测量，将诱导电压转换为磁化。可以使用这种具有成本效益的设计振动样品磁力计对磁氧化物进行分析。从VSM获得的数据可以得出结论设计的磁力计的成功操作。
The design and fabrication of a cost-effective vibrating sample magnetometer are explained. Improvement in the detected signal can be obtained using an operational amplifier circuit. The fabricated spiral detection coil design enhances the induced voltage obtained as shielding flux is reduced. A homemade setup is obtained by taking a woofer as an actuator and plexiglass as the vibrating medium. Lock-in amplifier analyzed the booster enhanced induced voltage signal by the principle of phase detection. Study of amplified and non amplified signals from the Nickel (99% purity) sample was done. Conversion of induced voltage to magnetization was done by calibration incorporating the coercivity and retentivity measurement. Magnetic oxide can be analyzed using this cost-effective designed Vibrating sample magnetometer. The data obtained from the VSM can conclude the successful operation of the designed magnetometer.
