In this chapter, we want to show that electric and magnetic fields depend upon the frame of reference from which they are observed. This fact will lead us to a deeper understanding of induction in moving conductors, as already described in Chap. 5 in

In our whole discussion of image formation and optical instruments, the details of lens fabrication and ray diagrams have not been emphasized; instead, we have used the limiting boundaries of light beams as an explanatory principle. This decisive poi

We return to the first experiment (in group 1) of Sect. 5.2, and reconsider induction in the simplest possible case: An induction coil with only one turn, i.e. an induction loop, is supposed to enclose a time-dependent magnetic field of flux density

Some black night in your darkened bedroom, stick your head under the covers and press on the corner of your eye. Then you will see a bright light, in the form of a colored, yellow, shining ring. The words printed here in italics are used by our natur

Textbooks on mechanics usually begin with the concepts of length, time, and mass. The measurement apparatus which has been tried and tested in everyday life is described, i.e. rulers, clocks and balances, and they are immediately put to use. No one u

Physics is and remains an empirical science. In optics, as in other areas, observations and experiments have to provide the starting points for concepts and physical laws. It is reasonable to begin our treatment of optics, as in other fields, with th

In 1676, Olaf Romer, a Dane, at that time tutor to the royal princes at the court of Louis XIV in Paris, discovered the finite propagation velocity of light. Based on astronomical observations, he obtained a value which is of the correct order of mag

Figure 9.1 serves to illustrate the general definition of the term current source or generator. A pair of condenser plates or “electrodes” A and C are connected through an ammeter. Between these electrodes are charges of both signs; we can think

Thus far, we have dealt only with electric fields in empty space. The presence of air molecules could be neglected in our considerations; their influence is felt only in the fourth decimal place by 6 digits. However, when we consider fields in insula

Thus far, we have considered magnetic fields only in empty space (the presence of air molecules had a negligible effect on our results. The influence of the air changes only the 6th place after the decimal by 4 units). Some of the current-carrying co
