Abstract

A magnetic setup able to characterize magnetic materials in distinct shapes has been implemented using the force magnetometry principle. It consists of a combination of two toroidal magnets, which move along their symmetric axis, and an analytical balance that supports a still sample. Based on the nominal features of the setup employed, the prototype presents a resolution ranging from 13 to 21 nAm², similar to a vibrating sample magnetometer. The feasibility of the system is demonstrated using powder samples. The magnetic field range of the developed device is a function of physical and mechanical features of the magnetic assembly.
