Abstract
Magnetic interactions, besides their intrinsic interest, constitute a didactical topic suitable to contextualize the fundamental physical concept of field. Moreover, the magnetic properties of matter, in particular ferromagnetism, are usually poorly dealt in italian high schools. By employing the Java programming language, we have developed an interactive tutorial allowing learners to explore the ways in which two GeomagTM magnets interact with a ferromagnetic sphere. The simulation (whose quantitative aspects are based on a magnetostatics transposition of the electrostatic’s method of images) interactively shows the sphere’s magnetization pattern as a magnetic dipole approaches to it. The interaction force between magnet and ferromagnetic object is also shown. The proposed tutorial is usefully employed to explain the so-called “Geomag paradoxes” (Defrancesco et al. 2007).
