The construction and demonstration of an electrostatic motor called Franklin's Bells. Benjamin Franklin worked on this motor as a detector for imminent lightning strikes.
using the capacitor analogy. if the e-field is constant inside the capacitor why wouid bringing the center conductor closer to the + plate make the force of attraction greater. isn't force = qE??
With the little bell in the center the electric field is no longer constant. In fact inside the little bell it is zero, it is a Faraday cage. If you have a dc voltage V across the capacitor, the integral of E dot dl from one plate to the other has to be V. So if your path of integration goes through the little bell, just outside the little bell the electric field has to be larger than the field would be without the bell present.
WoW. .. An electro static motor ... Great to see ... But electromagnetic motor takes very less energy than electrostatic motor... Isn't it? ... Why is this so?
more cow bell that's what we need
