Current and Magnetic Flux Densityvirtual surface on which the vector potential is the same is the equivector potential surface. The relationship between the equivector potential surface and the magnetic flux density is discussed. We also learn the magnetic properties of the magnetic moment produced by a small closed current, which appears in magnetic materials.Proponent 发表于 2025-3-25 10:33:46
Superconductorsthod of images, is introduced to determine the magnetic flux density outside the superconductor and the distribution of current on the surface in such given conditions. It is theoretically proved that the electrical resistivity of the superconductor is zero.Traumatic-Grief 发表于 2025-3-25 14:26:50

Electromagnetic Inductionce with a magnetic flux density .. The magnetic energy, which is covered in Chap. ., is estimated again from the electric energy that the electric power source supplies under the electromagnetic induction. Finally, the skin effect is discussed in association with the electromagnetic induction.无法治愈 发表于 2025-3-25 22:11:25
Displacement Current and Maxwell’s Equationsare determined by the electric potential and the vector potential, and the set of these potentials is called the electromagnetic potential. We introduce the Poynting vector that describes the flow of electromagnetic energy.Emmenagogue 发表于 2025-3-26 02:00:22

Conductors is no electric charge inside the conductor, and the conductor is equipotential. When an electric charge is given to the conductor, it is distributed only on the conductor surface, in such a way that zero electric field strength is attained. The same thing occurs when an external electric field is ainstitute 发表于 2025-3-26 14:44:57
Conductor Systems in Vacuume electric potential is generally described using the coefficients of electric potential or the capacity coefficients. The simplest conductor system is a capacitor composed of two conductors. The characteristic of the capacitor is given by the capacitance, i.e., the electric charge that can be store芭蕾舞女演员 发表于 2025-3-26 20:02:36
Dielectric Materials displaced along the direction opposite to the electric field, even though they are bonded by nuclei. This phenomenon is electric polarization. As a result, electric dipoles are produced and polarization charge appears. Thus, the electric field is produced by true electric charges and also by polari
