Calculate the raial ion transport flux n_i*v_i_r in a cylindrical hydrogen plasma which has an axial curent of 1MA unifmorly distributed over a plasma of radius a = 1 m, has a uniform temperature of Ti = Te = 2 keV, and has an axial magnetic field Bz = 5 T. Use n = 10^20 (m^-3) and ln (pyramid) = 20
