  I have performed an experiment which is a variant of the one suggested
recently by F. O. Minotti and T. E. Raptis. The aim of this experiment is to
check the generation of a pulsed gravitational potential by a transient
magnetic field as predicted by a scalar tensor theory of gravity. Such a scalar
tensor theory allows an enhanced coupling of its fundamental long-range real
scalar field as well as its external scalar field to the electromagnetic field,
according to the author's previous papers. Several possible sources that could
mimic the predicted effect have been ruled out. Finally, it seems likely that
the predicted effect is there with the right order of magnitude, as expected.
