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.
