CALL: MAGNETIC_FIELD


coordinates

  The coordinates system expected by MAGNETIC_FIELD is the internal
  frame. If you describe your cell in Cartesian coordinates, then
  the internal frame is simply the Cartesian coordinate system. If
  use polar coordinates however, then you should supply the following
  parameters:

  for x: log(r)
  for y: phi, in radians

field

  The field is returned in internal coordinates. The internal
  coordinates system is Cartesian when the cell is described in
  Cartesian coordinates, but when you describe the cell in polar
  coordinates, you've to apply the following mapping:

  Br = Bx/r
  Bphi = By/r
  Bz = Bz
