| contents | Effects of torsion on electromagnetic fields Laércio Dias Fernando Moraes Física, Astronomía y Matemáticas In this work, we investigate the effects of torsion on electromagnetic fields. As a model spacetime, endowedwith both curvature and torsion, we choose a generalization of the cosmic string, the cosmic dislocation.Maxwells equations in the spacetime of a cosmic dislocation are then solved, considering both the case of astatic, uniform, charge distribution along the string, and the case of a constant current flowing through the string.We find that the torsion associated to the defect affects only the magnetic field whereas curvature affects bothelectric and magnetic fields. Moreover, the magnetic field is found to spiral up around the defect axis. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435409 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.35 |
