Traversable wormholes, were they to exist for any length of time, would act as electric and gravitational Faraday cages, i.e. attenuate non-normal electric and gravitational field exponentially inside their throats with the scale parameter of the mouth size/throat circumference. Consequently, the electric/gravitational field around them is non-conservative. This follows straightforwardly from solving the Laplace equation, but never discussed in the literature as far as I can find.
