Recently Scientific Visualization together with Virtual Reality has rapidly become available as leading edge technologies. In the midst of this scenario the demand for educational software that offers support for the teaching process in many areas has greatly increased. This trend is not different in Electromagnetism. This paper presents an educational training system, which is an attempt towards answering this demand. The application has been embedded with both virtual reality technology and scientific visualization techniques in order to carry out interactive investigation and manipulation of concepts concerning electric charge and its electric field. The architectural aspects of such system are discussed jointly with the description of an experimental prototype called Electras.
