and a supercurrent is generated to expel the field from the rest of the material.
This supercurrent moves around these region in a vortex-like shape.
Please see the figure below for a beautiful drawing.

It was not specified what the direction of $\vec{B_E}$ was with respect to the cylinder orientation, so I chose what I thought was most reasonable as an example.

\caption{The direction of $\vec{J_s}$ is such that a magnetic field is generated to counteract and even expel the external field. Around the vortices, that menas that the supercurrents run anti-clockwise. Around the outside border of the cylinder, however, $\vec{J_s}$ runs clockwise to cancel $\vec{B_E}$.}
