Considering a localized steady current distribution, we make a Taylor expansion directly in the Biot–Savart law to obtain, explicitly, the dominant contribution of the magnetic field at distant points, identifying the magnetic dipole moment of the distribution. We also present a simple but general demonstration of the torque exerted by a uniform magnetic field on a current loop of general form, not necessarily planar. For pedagogical reasons we start by reviewing briefly the concept of the electric dipole moment. 1. Introduction The general concepts of electric and magnetic dipole moments are commonly found in our daily life. For instance, it is not rare to refer to polar molecules as those possessing a permanent electric dipole moment. Concerning magnetic dipole moments, it is difficult to find someone who has never heard about magnetic resonance imaging (or has never had such an examination).

    A Problem-Solving Approach – Chapter 2: the Electric Field

    chapter 2 the electric field 50 The Ekelric Field The ancient Greeks observed that when the fossil resin amber was rubbed, small light-weight objects were attracted. Yet, upon contact with the amber, they were then repelled. No further significant advances in the understanding of this mysterious phenomenon were made until the eighteenth century when more quantitative electrification experiments showed that these effects were due to electric charges, the source of all effects we will study in this text. 2·1 ELECTRIC CHARGE 2·1·1 Charginl by Contact We now know that all matter is held together by the aurae· tive force between equal numbers of negatively charged elec· trons and positively charged protons. The early researchers in the 1700s discovered the existence of these two species of charges by performing experiments like those in Figures 2·1 to 2·4. When a glass rod is rubbed by a dry doth, as in Figure 2-1, some of the electrons in the glass are rubbed off onto the doth. The doth then becomes negatively charged because it now has more electrons than protons.

If the positively charged glass rod is brought near a metal ball that is free to move as in Figure 2-2a, the electrons in the ball nt~ar the rod are attracted to the surface leaving uncovered positive charge on the other side of the ball.

    Temporal Analysis of Radiating Current Densities

    Temporal analysis of radiating current densities Wei Guoa aP. O. Box 470011, Charlotte, North Carolina 28247, USA ARTICLE HISTORY Compiled August 10, 2021 ABSTRACT From electromagnetic wave equations, it is first found that, mathematically, any current density that emits an electromagnetic wave into the far-field region has to be differentiable in time infinitely, and that while the odd-order time derivatives of the current density are built in the emitted electric field, the even-order deriva- tives are built in the emitted magnetic field. With the help of Faraday’s law and Amp`ere’s law, light propagation is then explained as a process involving alternate creation of electric and magnetic fields. From this explanation, the preceding math- ematical result is demonstrated to be physically sound. It is also explained why the conventional retarded solutions to the wave equations fail to describe the emitted fields. KEYWORDS Light emission; electromagnetic wave equations; current density In electrodynamics [1–3], a time-dependent current density ~j(~r, t) and a time- dependent charge density ρ(~r, t), all evaluated at position ~r and time t, are known to be the sources of an emitted electric field E~ and an emitted magnetic field B~ : 1 ∂2 4π ∂ ∇2E~ − E~ = ~j + 4π∇ρ, (1) c2 ∂t2 c2 ∂t and 1 ∂2 4π ∇2B~ − B~ = − ∇× ~j, (2) c2 ∂t2 c2 where c is the speed of these emitted fields in vacuum. See Refs. [3,4] for derivation of these equations. (In some theories [5], on the other hand, ρ and ~j are argued to arXiv:2108.04069v1 [physics.class-ph] 6 Aug 2021 be responsible for instantaneous action-at-a-distance fields, not for fields propagating with speed c.) Note that when the fields are observed in the far-field region, the contribution to E~ from ρ can be practically ignored [6], meaning that, in that region, Eq.

Calculate the resistance, current, electric field, and current density in a material knowing the material composition, geometry, and applied voltage. Calculate the power density and total power when given the current density and electric field. You can watch the video associated with this chapter at the following link: Historical Perspective: André-Marie Ampère (1775-1836) was a French physicist and mathematician who did ground-breaking work in electromagnetism. He was equally skilled as an experimentalist and as a theorist. He invented both the solenoid and the telegraph. The SI unit for current, the Ampere (or Amp) is named after him, as well as Ampere’s Law, which is one of the four equations that form the foundation of electromagnetic field theory. Photo credit: https://commons.wikimedia.org/wiki/File:Ampere_Andre_1825.jpg, [Public domain], via Wikimedia Commons. 1 10.1 Mathematical Prelude: Line Integrals As we saw in section 5.1, a surface integral requires that we take the dot product of a vector field with a vector that is perpendicular to a specified surface at every point along the surface, and then to integrate the resulting dot product over the surface. Surface integrals must always be a double integral, since they must involve an integral over a two-dimensional surface. We also have a special symbol for a surface integral over a closed surface, such as a sphere or a cube: (Copies of Equations 5.1 and 5.2) While a surface integral requires a double integral to be taken of a dot product over a surface, a line integral requires a single integral to be taken of a dot product over a linear path.

At the end of that course, you will have seen the full set of Maxwell's equations, which in vacuum are ρ @B~ r~ · E~ = r~ × E~ = − 0 @t @E~ r~ · B~ = 0 r~ × B~ = µ J~ + µ (1.1) 0 0 0 @t with @ρ r~ · J~ = − : (1.2) @t In this course, we will investigate the implications and applications of these results. We will cover • electromagnetic waves • energy and momentum of electromagnetic fields • electromagnetism and relativity • electromagnetic waves in materials and plasmas • waveguides and transmission lines • electromagnetic radiation from accelerated charges • numerical methods for solving problems in electromagnetism By the end of the course, you will be able to calculate the properties of electromagnetic waves in a range of materials, calculate the radiation from arrangements of accelerating charges, and have a greater appreciation of the theory of electromagnetism and its relation to special relativity. The spirit of the course is well-summed up by the \intermission" in Griffith’s book. After working from statics to dynamics in the first seven chapters of the book, developing the full set of Maxwell's equations, Griffiths comments (I paraphrase) that the full power of electromagnetism now lies at your fingertips, and the fun is only just beginning. It is a disappointing ending to PHYS 350, but an exciting place to start PHYS 352! { 2 { Why study electromagnetism? One reason is that it is a fundamental part of physics (one of the four forces), but it is also ubiquitous in everyday life, technology, and in natural phenomena in geophysics, astrophysics or biophysics.
