Description

The experiment P3.7.1.1 investigates the phenomenon of free electromagnetic oscillations. The damping is so low that multiple oscillation periods can be observed and their duration measured. In the process, the deviations between the observed oscillation periods and those calculated using Thomson’s equation

are observed. These deviations can be explained by the current dependency of the inductance, as the permeability of the iron core of the coil depends on the magnetic field strength.
