英文摘要：
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.
