The Aharonov-Bohm effect: predicted by theorists Yakir Aharonov and David Bohm in 1959, the effect is a phenomenon where electrons can be affected by electromagnetic potentials without coming in contact with actual force fields.

A 2007 experiment by Batelaan’s group showed that there is no force acting on the electrons.

That work is highlighted on the cover of the September issue of Physics Today, the journal of the American Institute of Physics, along with a feature article by Batelaan and Tonomura reviewing research into the little-understood phenomenon.
