Abstract :
The magnetic susceptibility change in heterogeneous magnetic materials as a function of the magnetic matter characteristics (grain size, chemical composition, concentration) and also of the sample shape is studied. Techniques for measuring weak susceptibilities are described. They are used to show the existence of macroscopic demagnetizing fields in rod specimens beyond a certain volume of magnetic matter
