A more complete hybrid model for the evolution of pulsars, which also includes the effect of Ohmic heating in the magnetosphere, is proposed. This model explains the ωversus ω diagram and predicts that the surface magnetic field strength changes from B ∝ (P/P)1/2 for short period pulsars to B ∝ (P/P)1/2 ∝ 1/√τ for longer period pulsars. For these pulsars the circulation quantum number of the vortex lines in the pulsar seems to be closer to the ground state of n = 1 than to any higher state. It is also shown that Bode's law for planetary magnetism is not applicable to pulsars and that the luminosity of the observed high energy radiation from Jupiter can be explained with this hybrid model.
