It is also important to note, however, that for static fields, i.e., more precisely when !D!t=0, all the steady-state experimental phenomena investigated by Biot and Savart, and Ampère are still accounted for with equations (4.5).

Electric fields The electric field is introduced into Coulomb's law [1.1b] as follows: 1/2 21/2 FE = qE. with 1 1/2 2 C. q Ek d = [1.2] E1/2 is the electric field created by the charge q1 in the place of q2 (the symbol E is reserved for the quantity that is the electric field). An electric fish species, can sense electromagnetic fields (EMFs). These species use EMFs to navigate, orient, and hunt for prey. Cables from operational marine renew-able energy (MRE) devices can add EMFs to the environment, on top of other anthropogenic sources such as underwa-ter telecom or power cables, while also adding to the Earth's natural field. MRE So-caaled "electromagnetic field" is just the matter field with abnormal genic configuration for it is affected by special genic configuration of positive matter by PNT action. And just ously, as in electromagnetic field analysis. This paper out-lines and describes the purpose of electromagnetic field analysis, and presents examples of product design and de-velopment. The future outlook for electromagnetic field analysis is also discussed. 2. E˝ec#!˜˛ag˚e#ic Fie˝d A˚a˝&"i" 2-1 Fundamental Equations of Electromagnetic Field 8. Atoms in Electromagnetic Fields Our goal in this chapter is to understand how atoms interact with electromagnetic fields. There will be several stages to our understanding. We start by looking at atoms in constant, background electromagnetic fields. Because these fields break various of an electric field. So, we can rephrase Faraday's law of electromagnetic induction by saying that a magnetic field, changing with time, gives rise to an electric field. Then, the fact that an electric field changing with time gives rise to a magnetic field, is the symmetrical counterpart, and is FIGURE 8.2 (a) The electric and magnetic of an electric field.
