Abstract

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.
