  We present how the angular momentum of light can play an important role to
induce a dual or anti-dual behaviour on a dielectric particle. Although the
material the particle is made of is not dual, i.e. a dielectric does not
interact with an electrical field in the same way as it does with a magnetic
one, a spherical particle can behave as a dual system when the correct
excitation beam is chosen. We study the conditions under which this induced
dual or anti-dual behaviour can be induced.
