Questions and Answers of Fundamentals Of Plasma Physics

The interatomic or intermolecular forces are usually represented in terms of a potential energy function V(r) such that F(r) = −dV(r)/dr. For neutral particles, at large internuclear distances,
Consider an initially uniform plasma in which the electron and ion number densities are each equal ton. By some external means, let a one dimensional perturbation occur such that the electrons in an
(a) Calculate the amount of energy released by the fusion of 1 g of deuterium according to the nuclear reactions indicated in (4.1), considering as end products 4He, 1H, and 1n. Assume that the two
Calculate the coulomb repulsion force and the associated electric potential energy due to the coulomb interaction of two deuterium nuclei when brought together at a distance of 10–14 m. What
In a MHD generator a plasma of conductivity a is driven with velocity u (in the x direction) across a magnetic field B (in the y direction). Two electrode plates, each of area A and separated by a
Using Maxwell equations (5.3) and (5.4) derive the charge conservation equationThis result shows that conservation of electric charge is already implied by Maxwell equations.Maxwell equations (5.3)
From Maxwell curl equation (5.2) derive the equationTherefore, (5.5) can be considered as an initial condition for (5.2) since, if ∇ · B = 0 at a given initial time, then (5.2) implies that this
Using Maxwell equations derive the following energy conservation law for electromagnetic fields, known as Poynting's theorem,for a linear isotropic medium, for which D = ∈E and B = μH. Give the
Consider the following Maxwell equations:For a general medium for whichwhere P is the polarization vector and M is the magnetization vector, show that the total electric charge density (ρt) and
