On the asymptotic balance between electric and magnetic energies for hydromagnetic relativistic flows Núñez Jiménez, Manuel Circuit theorems Fundamental constants Electric currents Electrical energy Circumstellar disks Magnetic energy Magnetohydrodynamics Special relativity Black holes Magnetic fields Producción Científica In the equations of classical magnetohydrodynamics, the displacement current is considered vanishingly small due to low plasma velocities. For velocities comparable to the speed of light, the full relativistic electromagnetic equations must be used. In the absence of gravitational forcings and with an isotropic Ohm’s law, it is proved that for poloidal magnetic field and velocity and toroidal electric field, the electric and magnetic energies tend to be equivalent in average for large times. This represents a partial extension of Cowling’s theorem for axisymmetric fields. 2019-12-18T12:45:13Z 2019-12-18T12:45:13Z 2013 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion PHYSICS OF PLASMAS 20, 062902 (2013) 1070-664X http://uvadoc.uva.es/handle/10324/39943 10.1063/1.4812197 062902-1 6 062902-7 Physics of Plasmas 20 1089-7674 eng https://aip.scitation.org/doi/pdf/10.1063/1.4812197?class=pdf Attribution-NonCommercial-NoDerivatives 4.0 Internacional info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ application/pdf American Institute of Physics https://uvadoc.uva.es/bitstream/10324/39943/4/PHP2013.pdf.jpg Hispana TEXT http://creativecommons.org/licenses/by-nc-nd/4.0/ UVaDOC.
