Geometry of different electromagnetic parts of Vibrating Sample Magnetometer (VSM) is a major factor of VSM output voltage. In this paper design, geometryoptimization and implementation of a sensitive, versatile and relatively inexpensive VSM system has been described. Considering all effective geometrical parameters in the systemoutput voltage, the induced voltage in the pick-up coils has been obtained analytically and the geometry of the pick-up coils hasbeen optimized for maximum output induced voltage. Two opposite series of pick-up coils, piezoelectric based vibrationsystem and required electronic circuits have been designed and the VSM system has been implemented. The implemented optimized VSM system has been used to reveal magnetization loop of ferromagnetic materials
