Abstract
Accurate measurements of the Abraham density force have been conducted in a BaTiO3 ceramic for the first time. The measured torque amplitudes (in the order of 10−10 Nm) were in good agreement with the predicted values inside the error limits of 10%. This conclusively rules out Minkowski's unsymmetric momentum-energy tensor for material media at low frequencies.Keywords
