An analytic solution for the force-free magnetic field, del x B = lambda B, in the poloidal divertor configuration of the Tokapole II device [Nucl. Fusion 19, 1509 (1979)] is presented. Experiments conducted on Tokapole II which provide equilibrium magnetic field profile measurements using a magnetic probe are then described. Observations include a non-constant-lambda profile and a large diamagnetic current near the divertor separatrix.
