Permittivity of common metals
WebThe dielectric constant k is the relative permittivity of a dielectric material. It is an important parameter in characterizing capacitors.It is unfortunate that the same symbol k is often used for Coulomb's constant, so one must be careful of this possible confusion.It is more typical of physics texts to use the form 1/4πε 0: for Coulomb's constant. WebFerromagnetic materials. The most important class of magnetic materials is the ferromagnets: iron, nickel, cobalt and manganese, or their compounds (and a few more …

WebA metal can be considered as an ionic lattice embedded inside an electron sea. The periodic ion lattice causes a periodic potential, which is very hard to calculate. Therefore, we often adopt the free electron model which treats the ions as a uniform background of positive charge even for real metals. This is called a free electron gas.
