Magnetic properties of materials,. s. Transport of electronic charge, of magnitude ., around a circuit in this time corresponds to an average electric current of . ~ 1 mA. Taking into account the very small radius of this orbit (. ~ 1/2 Å = 0.5 × 10. m) gives a much more modest figure for the magnetic dipole moment, ., of the current loop, namely . = . π. ~ 10. A m..

Relativity and electromagnetism,came to be seen as a perfect example of a fully developed relativistic theory. An appreciation of the relativistic nature of electromagnetism gives important insights into its theoretical structure as well as providing some techniques useful in its practical applications.

,Maxwell’s equations ,or the electric charge and electric current explictly referred to in the equations themselves. The qualification ‘.’ serves to make an important distinction between the fundamental equations of electromagnetism, dealt with in this chapter, and their more phenomenological extensions to material media described in Chapter 6.

https://doi.org/10.1007/978-981-13-9648-9 materials, belong more to condensed matter physics than to electromagnetism. The main electromagnetic interest lies in how a description of these properties leads to a phenomenological version of Maxwell’s equations, involving fields conceptually different from those considered so far.
