Electric Fields Experiment

The electric field is a vector quantity whose direction is taken to be the direction that this small positive test charge would move. Electric fields are produced by other charges or charge distributions. These are in turn created by the separation of charges by some electromotive force, emf, such as a battery or power supply. This is usually ...

Electric field (article) | Electrostatics | Khan Academy

The electric field is a vector quantity that exists at every point in space. The electric field at a location indicates the force that would act on a unit positive test charge if placed at that location. The electric field is related to the electric force that acts on an arbitrary charge by, The dimensions of electric field are newtons/coulomb, .

Electric Charge and Electric Field - Pearson

528 CHAPTER 17 Electric Charge and Electric Field An ion is an atom that has lost or gained one or more electrons. If one or more electrons are removed, the remaining positively charged structure is called a positive ion (Figure 17.3b). A negative ion is an atom that has gained one or more electrons (Figure 17.3c). This gaining or losing of electrons is called ionization.

This is just like the Electric field case except with F/q replacing E. The drift is therefore v d = 1 F ∧ B (2.21) q B2 In this case, if force on electrons and ions is same, they drift in opposite directions. This general formula can be used to get the drift velocity in some other cases of interest (see later). 2.3 Non­Uniform B Field

Electric field - Wikipedia

The electric field is defined at each point in space as the force (per unit charge) that would be experienced by a vanishingly small positive test charge if held at that point.: 469–70 As the electric field is defined in terms of force, and force is a vector (i.e. having both magnitude and direction), it follows that an electric field is a vector field.
