E1344: Oscillations between a site and a ring
... A given ring with length L = 1 has N sites, which have equal potential (V = 0). The hopping amplitude of a particle per time unit between neighbouring sites is c. Another site is added at the center of the ring. The relation energy of the particle in the central site is ε0 . The hopping amplitude pe ...

127 Magnetic monopole and magnetic charge
... we had to formulate: „There are no particles for which the volume integral of the divergence of the magnetic field strength over a region of space that contains the particle is different from zero.“ By the way, one could get rid of the electric charge in the same way. Obviously nobody would do so. O ...

Electric Shielding and the Electric Field
... Electric Shielding and the Electric Field Speaking of induction, we discussed a simple experiment with the ball on the silk thread and the charged rod. We saw that they affected each other at a distance. A similar effect is produced by magnets. We call the region of influence of magnetic forces surr ...

Activity 4 – Induction in an Aluminum Can
... In this activity, Lenz’s Law is demonstrated. Lenz’s Law states that an induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current. In this activity, an empty aluminum can floats on water in a tray, such as a Petri dis ...

... The force on the segment of the loop closest to the wire is towards the wire, since the currents are in the same direction. The force on the segment of the loop farthest from the wire is away from the wire, since the currents are in the opposite direction. Because the magnetic field varies with dist ...

Quantum rings are a kind of well-known mesoscopic systems having a great potential application.[1−6] Since their physical properties can be controlled, the physics involved is very rich, therefore they are also attractive in the academic aspect. Now the quantum rings containing only a few electrons ...

... farther away from a certain field point contribute less. The units of A are kgm/(Csec). Note that it is not a potential energy. It is sometimes referred to as a potential momentum. The field A shows up in the Hamiltonian when doing quantum mechanics. We will explain the meaning of A in a future chap ...
