... Pacs Number : 03.50.De ; 41.20.-q. It is true that Ampère’s formula is no more admissible today, because it is based on the Newtonian idea of instantaneous action at a distance and it leads notably to the strange consequence that two consecutive elements of the same current should repel each other. ...

... Now let’s look at how electricity is created when using a generator. A generator is a device that converts mechanical energy into electrical energy. The process is based on the relationship between magnetism and electricity. In 1831, English physicist Michael Faraday discovered that when a magnet mo ...

... F = (1/[40])q1q2 / r 2 is called the permittivity of free space. In general, different materials have different permittivities , and Coulomb’s law has a more general form: F = (1/[4])q1q2 / r 2. If the two electrons are embedded in a chunk of quartz, having a permittivity of 120, what will the ...

Hall effect



The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
