This chapter discusses the principles of magnetic field of electric current. Electric currents create magnetic fields. This discovery by Oersted has been described quantitatively in two distinct ways: (1) Biot and Savart proposed a relation in differential form that is somewhat analogous to a ...
Try to think in three dimensions. Current flow in the antenna wire creates the magnetic field lines. The voltage across the two segments of the antenna produces the electric field lines. The picture is somewhat simplified if we just show the field lines as in Fig. 7.3B. The electric and ...
remote electric fieldmagnetic fieldreturn-stroke modelexact expressionsleadercharge densityWe derive exact expressions for remote electric and magnetic fields as a function of the time- and height-varying charge density on the lightning channel for both leader and return-stroke processes. Further, we ...
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...

Applied electric fields align the molecules. The resulting charge displacement reduces the electric field in the material and modifies fields in the vicinity of the dielectric. There are corresponding magnetic field effects in paramagnetic and ferromagnetic materials. These materials contribute to magnetic ...
