  In the more than 100 years-old Abraham-Minkowski problem in macroscopic
electrodynamics, the issue of how to observe the so-called Abraham term ${\bf
f}^{\rm Aterm} = [(\varepsilon\mu-1)/c^2] \partial/\partial t ({\bf E}\times
{\bf H})$ has been a main point. Recent years have seen a number of beautiful
experiments in radiation optics, but these experiments usually give no
information about the Abraham term as this term simply fluctuates out. So one
is left with somewhat indirect verifications of this force, as in the radiation
pressure of Jones {et al.} in the 1950's, testing the radiation pressure on a
mirror immersed in a dielectric liquid. Now, there is a different way to test
the existence of ${\bf f}^{ \rm Aterm}$, namely to work with low
(quasi-stationary) frequencies enabling one to observe the sinusoidal variation
of the force directly. These kind of experiments were actually done by Walker
{\it et al.} in 1he 1970's, using BaTiO$_3$ as a high-frequency dielectric
(permittivity $\varepsilon \sim 3600$). Now, in recent years there have
appeared dielectric materials with giant permittivities, of order $10^5$ or
even higher. It is therefore natural to consider the idea of Walker {\it et
al.} anew, in order to test if this demanding experiment can be facilitated and
give better accuracy. That is the main topic of the present paper. The positive
outcome of these kinds of experiments clearly supports the Abraham
energy-momentum tensor at low frequencies. The Minkowski tensor is unable to
predict a torque at all. The low-frequency and the high-frequency regimes are
in this way highly contrasted, as it is obvious that in optical experiments the
Minkowski tensor is by far the simplest and most convenient one to use. We end
this note by commenting upon the use of the Einstein-Laub tensor (1908) in
explaining this experiment, and discuss also the influence from air friction.
