Resumo: A simple system to measure the magnetic susceptibility of different materials is presented. The system uses an analytical scale with sensitivity on the order of micrograms and a permanent NdBFe magnet, based in the Rankine method. In this apparatus, the sample is placed near to the magnet that is fixed on the scale. Depending on the magnetic properties of the sample, an attractive or repulsive force will appear between the magnet and the magnetizing sample. Measuring this force, registered by the scale as a mass, the magnetic parameters such as: permeability and susceptibility of the sample can be determined. Despite it is simplicity the method is quantitative, precise and easily reproducible in many laboratories, what makes it attractive for teaching experiments.
