Electric Field Sources or Generators

To create source of magnetic field. You only need wires as the current passing thru them can create it. The electric field in the wires is null because there is a cancellation inside the positive lattice and electrons.

I'd like to build a very strong source of electric field only. Can I use two big kitchen plates and connect each of them to positive and negative of a car battery? Would this create electric field in the middle.

Pls. mention all sources that produce electric fields with minimal magnetic field present. Beside the capacitor concept. How else could you creates source of electric field where the electrons charge become bare and no cancellation from the atomic lattice.

Does this mean there are positive and negative sources of electric field that can be built using circuits. For example, if you force out electrons from a certain material, does it produce a positive electric field from the positive ions left? What materials can do this?

Thanks.

yes

the most obvious ones are van de graff generators that can create very large fields with a tiny current by moving electrons from one electrode to the other.

sure, any circuit that moves electrons creates an electric field. however if you start with neutral matter you end up with symmetric positive and negative charges, you can only separate them not create them separately. any material can do this, its just easier with some than others and it depends on what you are trying to do.

Rub your feet on the carpet during a dry day.

van de Graff generator (DC continuous). Wimshurst generator (DC continuous or pulsed). Marx generator (DC pulsed). Tesla coil (kHz AC). Snap together 100 transistor batteries in a row - that's 900 V end to end (DC continuous).

Sure, 12 whole volts, except for the plates. 12 V can kill you.

You shouldn't be trusted with anything electrical until you have something useful between your ears.

Moderate potential on a small conducting sphere. Point of a needle. The sharp edge of a razor blade.
