Abstract
This paper describes a vibrating sample magnetometer (VSM) intended to measure the magnetic moment of large permanent magnets. The reciprocity theorem was used to preview the pick-up coils output voltage. The finite element method was utilized to determine the magnetic field produced by a unitary current in the pick-up coils. The sensitivity of the magnetometer was determined by the measurements carried out with a well characterized sample.
