Does a Battery on a Table Create an Electric Field?

AI Thread Summary
A battery on a table does produce an electric field in its vicinity, even without a conductor connecting its terminals. The electric field generated is similar to that of a capacitor, with the field lines extending from the positive terminal to the negative terminal. The magnitude of the electric field can be analyzed using Gauss's law. Understanding the behavior of the electric field around a battery is essential for grasping basic electrical concepts. Overall, a stationary battery does create an electric field.

A battery lies on a table. Does it produce an electric field in its vicinity when no conductor connects its terminals together? If yes, do you have an idea of its magnitude?

Thanks.

yes it has an E field , It would be similar to a capacitor , and the E field would go from + to minus.
Maybe you could use gauss's law .

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
