  This is a review addressed to undergraduate students of electrical
engineering and physics careers, and our aim is to present a pedagogical
integration of some knowledge acquired in electromagnetism and
electromechanical energy conversion courses, and to show how they can be used
in actual technological applications, in particular for microscopic and
nanoscopic systems.In this work, we present a conceptual analysis of the
generation of optical forces and torques over a system of particles irradiated
by an external electromagnetic field, studying the induced dynamics.
