This experiment enables your smartphone to qualitatively measure the hysteresis curve of an iron core. The iron core is sitting inside a coil. By running a current through the coil the iron core is magnetised. When plotting the current running through the coil against the magnetic field of said coil, a hysteresis effect becomes visible. The current is indirectly measured by the magnetic field of a second coil without iron core, set in a different axis.
