... The dielectric constant (εr’) is the ratio of the capacity of an electric capacitor filled with the substance to that of the same capacitor in vacuum, at a definite external field frequency. Dielectric loss is associated to the part of the energy of an electric field that is dissipated irrecoverably ...

... Hefei 230026, P. R. C The effects of electron pressure tensor and electron inertia at tearing mode with guide magnetic field are analyzed systematically in electron magnetohydrodynamics. The behavior of tearing mode depends not only on the magnitude of pressure gradient, but also on the relative mag ...

... • because the force field is conservative, the work that is done can always be expressed in terms of a potential energy U . When the particle moves from a point where the potential energy is Ua to a point where it is Ub , the work Wa→b done by the force is Wa→b = Ua − Ub . • the work-energy theorem ...

... Note: We should be a little cautious about our definition of the magnetic flux, Φ = B This is only true when the magnetic field is constant over the area; however, it does give us some conceptual insight to this problem. The induced current in the circuit is zero. (b) If on the other hand the curren ...

... Therefore, if the functions ψn, l, ml and ψn 0 , l 0 , ml have the same azimuthal quantum number, i.e. parity, their product has parity +1. The z operator however changes its sign under a spatial inversion and the integration of the scalar product vanishes, because Z+a dx f (x) g(x) ≡ 0 . |{z} |{z} ...
