A simple apparatus able to measure the magnetic susceptibility of spherical samples is demonstrated. The method is based on the equilibrium of the magnetic force applied on the specimen from a coil, and of the Stoke's force applied on the specimen by the flow of a liquid. Acquiring basic materials (coil, tube, power supply), we measured with sufficient accuracy the magnetic susceptibility of materials with unknown magnetic properties. Furthermore, by using a spherical specimen with given magnetic susceptibility, following the reverse methodology, it is possible to define the viscosity of the fluid. Thereby, we present a simple, low cost technique for fast and efficient measuring of specimens' magnetic susceptibility or viscosity of the liquid where the specimen is located.
