Angular momenta dynamics in magnetic and electric
... momentum are often easier to solve. This makes it possible to treat a whole class of problems, which, from a quantum theory viewpoint, are extremely complicated. For example, one such problem is the interaction of intense laser radiation with molecules in an external electric or magnetic field; see, ...

Measuring Fractional Quantum Hall Effect
... field, Klaus von Klitzing and collaborators in 1980 found that in two dimensions this dependence looks much different[1]. Working in two dimensions and a regime of very low temperatures (below 4 K) and high magnetic fields (1−10 T ), they observed a stepwise dependence of RH on magnetic field streng ...

Development of Electro-Magnetic Brake System
... • Inversely proportional to the length of air gap between the poles. In general, an electromagnet is often considered better than a permanent magnet because it can produce very strong magnetic fields and its strength can be controlled by varying the number of turns in its coil or by changing the cu ...

Although these methods are consistent with and closely related to the one described here, they are not as well suited to the simplified analysis of many more complicated problems. The extensive and explicit use of the rotating coordinate system was ...
