  1. Kivelson and Russell 2.5.
  2. Kivelson and Russell 2.6.
  3. Using the magnetic field line equations, write the magnitude of the dipole magentic field in terms of the :
    1. L paramter and radial distance r,
    2. L parameter and the latitude λ.
  4. Consider a B field that is purely in the x-direction with the form:
     B(z) = B0 tanh(z/d) 
    Find the current density (magnitude and direction) and the plasma pressure distribution for this equilibrium.
