The electrons flow into the cathode and round a wire towards the anode, creating an electrical current.

Buckyballs trap electrons, but they can't make electrons flow.

As the negatively charged electrons flow in one direction around this circuit, the positively charged metal ions flow in the opposite direction in the electrolyte.

As the electrons flow from the coil, a voltage difference develops between the central electrode and side electrode.

Electrons flow through that digit's grid and strike those plates that are at a positive potential.
