Construction and calibration of a low cost and fully automated vibrating sample magnetometer

• A low cost automated vibrating sample magnetometer VSM has been constructed.
• The VSM records the magnetic hysteresis loop up to 8.3 KG at room temperature.
• The VSM has been calibrated and tested by using some measured ferrite samples.
• Our VSM lab-built new design proved success and reliability.

A low cost vibrating sample magnetometer (VSM) has been constructed by using an electromagnet and an audio loud speaker; where both are controlled by a data acquisition device. The constructed VSM records the magnetic hysteresis loop up to 8.3 KG at room temperature. The apparatus has been calibrated and tested by using magnetic hysteresis data of some ferrite samples measured by two scientifically calibrated magnetometers; model (Lake Shore 7410) and model (LDJ Electronics Inc. Troy, MI). Our VSM lab-built new design proved success and reliability.
