Influence of EM fields on classical friction?

looka

So, is there any? Friction being derived from EM forces of particles, does charging the surface of moving object macroscopically either electrically or magnetically result in any change of friction coefficient? Maybe altering / dynamic charge? Any measuring done there (I couldn't find any)?

It would be neat to reduce vehicle drag, so any way to significantly reduce air friction would be great news! Oil prices these days!
