a isothermal plasma is confined between the planes x=+-a in a magnetic field B=B, Z. sensity distribution is A) Derive an expression for the electron diamagnetic drift velocity vp as a function of x. B) Draw a diagram showing the density profile and the direction of vpe on both sides of midplane if B is out of the paper. C) Evaluate vp at x=a/2 if B=0.5T, KT,=10ev and a=7cm.
