  It is known that the Meissner-like effect is seen in a magnetosphere without
an electric current in black hole spacetime: no non-monopole component of
magnetic flux penetrates the event horizon if the black hole is extreme. In
this paper, in order to see how an electric current affects the Meissner-like
effect, we study a force-free electromagnetic system in a static and
spherically symmetric extreme black hole spacetime. By assuming that the
rotational angular velocity of the magnetic field is very small, we construct a
perturbative solution for the Grad-Shafranov equation, which is the basic
equation to determine a stationary, axisymmetric electromagnetic field with a
force-free electric current. Our perturbation analysis reveals that, if an
electric current exists, higher multipole components may be superposed upon the
monopole component on the event horizon, even if the black hole is extreme.
