John,
The neon and flourescent lights are arcs i.e. streams of charged particles
and that constitute an electric current which, in turn, produces a magnetic
field that interacts with the magnet. Magnetic fields can cause very small
(emphasize SMALL) effects on light such as rotating the plane of
polarization of polarized light (Faraday Effect) and causing splitting of
spectral lines (Zeeman Effect). I know of no
effect which would cause an observable bending of light rays by magnetic
fields. Gravitational field cause the bending of light rays but you need a
very large field such as produced by a neutron star (too heavy to carry in a
camera bag ;-)) or a black hole.
