  Quantum polarization effects associated with the conformal anomaly in a
static magnetic field background may generate a transverse electric current in
the vacuum. The current may be produced either in an unbounded curved spacetime
or in a flat spacetime in a physically bounded system. In both cases, the
magnitude of the electric current is proportional to the beta-function
associated with renormalization of the electric charge. In our article, we
investigate the electric current density induced by the magnetic field in the
vicinity of a Dirichlet boundary in the scalar QED. Using first-principle
lattice simulations we show that the electric current, generated by this
`conformal magnetic effect at the edge' (CMEE), is well described by the
conformal anomaly provided the conformal symmetry is classically unbroken.
Outside of the conformal limit, the current density is characterized by an
anomalous power law near the edge of the system and by an exponential
suppression of the current far away from the edge.
