Lecture 6 : Potential - University of Central Florida
... The electric potential difference does not depend on the integration path. So pick a simple path. One possibility is to integrate along the straight line AB. This is easy in this case because E is constant and the angle between E and dl is constant. ...

Magneto-transport properties of quantum films
... •Localized states in the tails cannot carry current. • Consequently, only extended states below the Fermi level contribute to the transport. Thus is why Hall conductance is frozen and does not depend on the filling factor! • Localized states in the tails serve only as reservoirs determining the Ferm ...

Chapter 10 Faraday’s Law of Induction
... E ⋅ d s is path-independent, which implies v∫ E ⋅ d s = 0 . Faraday’s law shows that as magnetic flux changes with time, an induced current begins to flow. What causes the charges to move? It is the induced emf which is the work done per unit charge. However, since magnetic field can do not work, as ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
