We made a detailed study of the properties of the electron
layer near the quark surface of strange stars with strong
( G) magnetic fields. The electrostatic potential and
the electric field at the quark surface were calculated as functions
of the magnetic field intensity of bare strange stars. Using an
ultrastrong (
G) magnetic field, we found
that the distribution of electrons becomes an exponential function
of radial distance, which is quite different in a magnetic
field-free case. We also calculated the variation in gap width
between the strange core and the normal nuclear crust for strange
stars, which is due to magnetic field effect.
