Faraday`s Law of Electromagnetic Induction
... This electromotive force acts as the driving force for the current induced in the closed circuit C, and Faraday’s law states that this emf results from any change in the magnetic flux linking that circuit. Notice that the mathematical expression (3) of Faraday’s law is a statement of an independent ...

Chapter 29 Faraday’s Law
... Michael Faraday formulated his law of induction. • It had been known for some time that a current could be produced in a wire by a changing magnetic field. • Faraday showed that the induced electromotive force is directly related to the rate at which the magnetic field lines cut across the path. ...

Maxwell`s Equations
... There’s a long history of people trying to derive Maxwell’s relations from something more concise. For example, Heras (AJP 75 p 652) demonstrates that more generally, if you have a scalar a vector “source” that are time dependent and related by a continuity equation, then you can define associated f ...

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.
