Water bending with comb: but where do the electrons go?

[QUOTE="sophiecentaur, post: 6437016, member: 199289"] That's the proper term for it. (We were taught it in school and its in all those textbooks.) It's not to be confused with an emf induced in a moving conductor. The charge separation is 'induced' by the applied field. Needless to say, in the environment of a laboratory sink, the humidity will cause leakage but the loss of charge is not due to the induced charge displacement on the water stream. The force, due to the charge imbalance is small, which is why it only works for a narrow free falling stream of water or small items like dust. If you look at that link on the electrophorus you'll see one other example that can give you spark after spark without having any effect on the surface charge of the dielectric one its base. The Whimshurst Machine is another more impressive use of the effect. [/QUOTE]
