Answer to Question #38947 in Electromagnetism for George
The experiment where one observes the electric field. You have a petri dish with fine oil in it and seeds. Than you send an electric charge trough the oil and so the seeds align.
But why does the oil condense around the needle which is the source of the field? What happens with the oil on a molecular level so it condenses?
