Froni recent investigations, the magnetic force generated by a heterogeneous high magnetic field has been high-lighted, in particular by levitating systems. This paper is devoted to describing a new method for the analysis of the magnetic properties of liquids by using the magnetic force. This technique has consisted of observing and measuring the transport of a paramagnetic or diamagnetic liquid under the gradient of high magnetic fields. The theoretical approach of this phenomenon has been de-veloped taking into account the fluid motion expanding in an axially symmetrical magnetic field. From this investigation, a typical experiment has been carried out by injecting a small amount of paramagnetic copper sulfate solution in a cell settled inside the bore of a superconducting magnet Consequently, the accordance between the experimental results and the theoretical expectations has led to the determination of the magnetic susceptibility of the solution in a short time.
