  The scalar-tensor theory of gravitation proposed by Mbelek and
Lachi\`{e}ze-Rey have been recently shown to lead to some remarkable effects
beyond those initially explored by its authors. These new effects include a
possible explanation of the forces measured in asymmetric resonant microwave
cavities, and the variation of the amplitude of electromagnetic waves as they
propagate in static electric or magnetic fields. These rather unique effects
are excelent candidates for laboratory tests of this particular type of
scalar-tensor theory. In the present work we introduce an additional remarkable
effect of the theory: the generation of pulsed gravitational forces by
transient, quasi-stationary electromagnetic fields. In particular, we explore
the possible measurable effects of the simple experiment of turning on and off
the current in a coil. We show that with the proposed values of the constant in
the theory, this effect could resonantly excite a pendulum oscillation up to an
easily measurable magnitude.
