(F. F.Chen 3.6) An isothermal plasma is confined between the planes x=±a in a magnetic field B=B0uz. The density distribution is n(x)=n0(1x2/a2).

(a) Derive an expression for the electron diamagnetic drift velocity, as a function of x.

(b) Draw a diagram showing the density profile and the direction of the electron diamagnetic drift on both sides of the midplane, if B points out of the paper.


(c)Evaluate vD at x=a/2$,if\(B=0.2 T, kTe=2$eVand\(a=4 cm.
