explain the electric field?

Question

I am having trouble understanding electric flux and the electric field.. no copy and paste,, Perhaps use ms paint to make a diagram.. I am in an advanced physics course and am struggling horribly.

Answer 1

The electric field is something that exists throughout all space, and only charges can interact with it.



The electric field is something used to help describe 'action at a distance'.



Imagine two charges separate from each other, both charges experience a force, however they are not touching. The electric field is needed to describe why they experience a force.



The electric field strength is defined as the force experienced per charge Q, sitting in that field.

E=F/Q



The electric flux can be seen much like a flux of water.

Here the flux (flow) of water is the amount of water passing through an area.



Just as with water, the electric flux is the amount of electric field passing through an area.

The stronger the electric field - the higher the flux, per unit area.

Imagine flux as a flow of the electric field.



Flux = E*A

Answer 2

Fields are the medium through which waves propagate. They exist at every point in space-time, but they are elementary and cannot be understood as anything more simple. Fields are not something that can be understood from deeper principles, but instead these are objects that had to be discovered. Some fields are more fundamental than other fields, every field descends ultimately from some field.



Now we understand that electric and magnetic fields are related by Special Relativity and in fact arise from an "Electromagnetic Gauge Potential" which itself is a field, but is more fundamental than the electric or magnetic field, since both can be derived from it.



Without charges, the electric field would be zero. Charges create a non-zero electric field according to Maxwell's equations. But the field exists independently of charges. In fact, it is possible to have no charged particles, but have fields that are non-zero.



Particles are understood to be quantum excitations of fields. Photons are the excitations of the electric and magnetic fields. There is an electron field which can create an electron.

Answer 3

it particularly is honestly any incorrect way around. Einstein stated that the magnetic container grow to be the relativistic manifestation of the electrical powered container. Maxwell's Equations coach the mathematical dating between them. you won't be able to create the electrical powered container around a proton with a changing magnetic container, by using fact the sphere might choose to be increasing consistently with out decrease. See the 0.33 reference for a proof of magnetism on the quantum scale.
