  Both neutron stars and strange stars are capable of supporting fast rotations
observed in pulsars. On the basis of this it has been argued that some of the
pulsars could be strange stars. We investigate whether strange stars can
sustain characteristic pulsar magnetic fields ($10^8 - 10^{13.5} Gauss$) over
astronomically significant time-scales. Furthermore, we check whether strange
stars fit into the general scenario of field evolution of pulsars. It is found
that as far as the evolution of the magnetic field is concerned the strange
pulsar hypothesis runs into serious difficulties to explain the observational
data.
