Electric flux , property of an electric field that may be thought of as the number of electric lines of force or electric field lines that intersect a given area. Electric field lines are considered to originate on positive electric charges and to terminate on negative charges.

## Gauss's law

Baird, Christopher S. Last reviewed: May The interaction among all electrically charged objects, objects with magnetic moments, and the electromagnetic field. The electromagnetic interaction is one of the four fundamental interactions of the universe. This interaction encompasses all physical phenomena related to electricity, magnetism, electromagnetic fields, light, and atoms Fig. As such, electromagnetism forms the fundamental basis for a wide variety of sciences, including solid-state physics, optics, chemistry, and molecular biology.

Gauss's law, infinite homogenous charge distributions and Helmholtz theorem. We rediscuss the validity of Gauss's law in the case of homogenous discrete and continuous charge distributions fulfilling all space. Keywords: classical electromagnetism, electrostatics, Gauss's law. In physics, some questions that we can formulate though frequently not realizable from a practical point of view, must as a matter of principle be satisfactorily answered. Moreover, they can be pedagogical useful tools and help the teacher to introduce new topics or discuss particularly hard ones. The answer given in [1] though correct is nevertheless intriguing.

All four of Maxwell's equations are now in place. This is an appropriate place to review their meaning and significance.

In physics , Gauss's law , also known as Gauss's flux theorem , is a law relating the distribution of electric charge to the resulting electric field. In its integral form, it states that the flux of the electric field out of an arbitrary closed surface is proportional to the electric charge enclosed by the surface, irrespective of how that charge is distributed. Even though the law alone is insufficient to determine the electric field across a surface enclosing any charge distribution, this may be possible in cases where symmetry mandates uniformity of the field. Where no such symmetry exists, Gauss's law can be used in its differential form, which states that the divergence of the electric field is proportional to the local density of charge. The law was first [1] formulated by Joseph-Louis Lagrange in , [2] followed by Carl Friedrich Gauss in , [3] both in the context of the attraction of ellipsoids. It is one of Maxwell's four equations , which form the basis of classical electrodynamics. Gauss's law has a close mathematical similarity with a number of laws in other areas of physics, such as Gauss's law for magnetism and Gauss's law for gravity.

This was his escape from a dreary life running a flour mill on the outskirts of Nottingham, England, in The tall wind mill owned by his father required hour attention, with farmers depositing their grain at all hours and the mechanisms and sails needing constant upkeep. During his one year in school when he was eight years old he had become fascinated by maths, and he had nurtured this interest after leaving school one year later, stealing away to the top floor of the mill to pore over books he scavenged, devouring and exhausting all that English mathematics had to offer.

It seems to me that his addition to the laws two of them are not significant enough to make it bear his name. As you noticed, separate equations have other names as well. Maxwell's adding the displacement term made the system complete, with all important consequences, in particular, existing of electromagnetic waves.

### About the History of Electrodynamics

Source Citation: "Magnetism. Gale Research, Reproduced in Discovering Collection. Farmington Hills, Mich. December, Magnetism and electricity represent different aspects of the force of electromagnetism, which is one part of Nature's fundamental electroweak force. The region in space that is penetrated by the imaginary lines of magnetic force describes a magnetic field.

These two complimentary proofs confirm that the Law of Universal Magnetism is a valid equation rooted in Gaussian law. The paper also confirms the theoretical existence of the magnetic monopole and calculates its magnetic charge using the ratio of the electromagnetic field and the speed of light. Using the mass-to-charge ratio of an electron, the mass and radius of the magnetic monopole are determined. The monopole is found to have the same radius as the electron and can also be found in the electromagnetic spectrum range known as gamma rays. Lightning is a natural source of gamma rays and could prove fruitful in the search for monopoles.

MathOverflow is a question and answer site for professional mathematicians. It only takes a minute to sign up. Does any one know actual references for the discovery of Gauss' Law a corollary of the Divergence Theorem? In the case of the divergence theorem, only dates are given, no references. I couldn't find anything in the collected works of Lagrange around that seemed to be close to any form of the divergence theorem. In the case of Gauss' law, a reference is given to the book by Balone, "A Word on Paper: Studies on the Second Scientific Revolution", but no page reference is given; the only index entry for Gauss is a brief mention of his name in connection with some one else; and perusing through the subject matter makes it seem very unlikely that anything about Gauss' law is in this book.

Но если не считать его изрядно устаревших представлений о рыцарстве, Дэвид, по мнению Сьюзан, вполне соответствовал образцу идеального мужчины. Внимательный и заботливый, умный, с прекрасным чувством юмора и, самое главное, искренне интересующийся тем, что она делает. Чем бы они ни занимались - посещали Смитсоновский институт, совершали велосипедную прогулку или готовили спагетти у нее на кухне, - Дэвид всегда вникал во все детали.

Провал. Мысль о том, что придется отстоять в очереди несколько часов, была невыносима. Время идет, старик канадец может куда-нибудь исчезнуть. Вполне вероятно, он решит поскорее вернуться в Канаду.

- Клянусь, я сделаю. Этим я и занимался сегодня весь день - считывал тексты с его терминала, чтобы быть наготове, когда он сделает первый шаг, чтобы вмонтировать этот чертов черный ход. Вот почему я скачал на свой компьютер его электронную почту. Как доказательство, что он отслеживал все связанное с Цифровой крепостью. Я собирался передать всю эту информацию в прессу.

А ждет его именно. Он скрыл информацию от директора, запустил вирус в самый защищенный компьютер страны, и, разумеется, ему придется за это дорого заплатить. Он исходил из самых патриотических соображений, но все пошло вкривь и вкось.

Повисла тишина. Наконец Нуматака спросил: - Где ключ. - Вам нужно знать только одно: он будет найден. - Откуда такая уверенность.

Даже если файл Танкадо будет прочитан прямо сейчас, это все равно будет означать, что АНБ идет ко дну. С такими темпами шифровалка сумеет вскрывать не больше двух шифров в сутки. В то время как даже при нынешнем рекорде - сто пятьдесят вскрытых шифров в день - они не успевают расшифровывать всю перехватываемую информацию.

Губы Стратмора приоткрылись, произнеся последнее в его жизни слово: Сьюзан. Воздух, ворвавшийся в ТРАНСТЕКСТ, воспламенился. В ослепительной вспышке света коммандер Тревор Стратмор из человека превратился сначала в едва различимый силуэт, а затем в легенду.

Он увидел уборщика и подошел к. - Has visto a una nina? - спросил он, перекрывая шум, издаваемый моечной машиной.  - Вы не видели девушку.

Вернусь завтра. И уже утром мы сможем поехать. В нашем распоряжении будет целых два дня. - Но я уже забронировала номер, обиженно сказала Сьюзан.

Лицо его было несчастным. - Я думал, вы из городского… хотите заставить меня… - Он замолчал и как-то странно посмотрел на Беккера.  - Если не по поводу колонки, то зачем вы пришли. Хороший вопрос, подумал Беккер, рисуя в воображении горы Смоки-Маунтинс.

Цифровая крепость исчезнет бесследно.
