... Electrostatics and Magnetostatics tensor can be changed by the addition of an arbitrary diagonal tensor, q i,k → q i,k + a · δ i,k , without any change in the potential. As a result, for l = 2 there are ... by a factor ε. For a parallel plate condenser, for example, the capacity becomes: C = εε 0 F d . This enhancement is often considerable, and in practice a dielectric material, su...
