  2. Electrostatic induction - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_induction

    Therefore electrostatic induction ensures that the electric field everywhere inside a conductive object is zero. A remaining question is how large the induced charges are. The movement of charges is caused by the force exerted on them by the electric field of the external charged object, by Coulomb's law .

  3. Static electricity - Wikipedia

    en.wikipedia.org/wiki/Static_electricity

    Electrostatic discharge while fueling with gasoline is a present danger at gas stations. [24] Fires have also been started at airports while refueling aircraft with kerosene. New grounding technologies, the use of conducting materials, and the addition of anti-static additives help to prevent or safely dissipate the buildup of static electricity.

  4. Kelvin water dropper - Wikipedia

    en.wikipedia.org/wiki/Kelvin_water_dropper

    The higher the charge that accumulates in each bucket, the higher the electrical potential on the rings and the more effective this process of electrostatic induction is. [2] During the induction process, there is an electric current that flows in the form of positive or negative ions in the water of the supply lines.

    the constant is the permeability of free space, commonly called , divided by ; in the absence of magnetically reactive insulation the value 200 is exact when using the classical definition of μ 0 = 4π × 10 −7 H/m, and correct to 7 decimal places when using the 2019-redefined SI value of μ 0 = 1.256 637 062 12 (19) × 10 −6 H/m.

  7. Coefficients of potential - Wikipedia

    where the c ij with i = j are called the coefficients of capacity and the c ij with i ≠ j are called the coefficients of electrostatic induction. [1] For a system of two spherical conductors held at the same potential, [2] = (+), = (+)

  8. Electrostatics - Wikipedia

    en.wikipedia.org/wiki/Electrostatics

    The electrostatic field (lines with arrows) of a nearby positive charge (+) causes the mobile charges in conductive objects to separate due to electrostatic induction. Negative charges (blue) are attracted and move to the surface of the object facing the external charge. Positive charges (red) are repelled and move to the surface facing away ...

  9. Line of force - Wikipedia

    en.wikipedia.org/wiki/Line_of_force

    A tube of force, also called a tube of electrostatic induction or field tube, are the lines of electric force which moves so that its beginning traces a closed curve on a positive surface, its end will trace a corresponding closed curve on the negative surface, and the line of force itself will generate an inductive tubular surface.
