For the equilibrium theta pinch produced by an azimuthal current in the theta direction (J ),

Question:

For the equilibrium theta pinch produced by an azimuthal current in the theta direction (J_θ), as illustrated in Fig. 6 of Chapter 12, determine expressions for the radial distributions of J_θ(r) and p(r) in terms of B_z(r). Draw a diagram illustrating these radial distributions for the special case when B_z is constant.
