As a generalization of the Pure Gravitational Field, is it possible to have a Pure Magnetic Field, or Pure Electric Field, or Pure Electromagnetic Field, etc. without matter in its proximity?

from astrophysical observations Susmita Jana ∗ and S. Shankaranarayanan † Department of Physics, Indian Institute of Technology Bombay, Mumbai 400076, India Abstract Non-minimal coupling between the Riemann curvature and the electromagnetic field appears as quantum corrections when gravity is coupled to the standard model of particle physics. The non-minimal coupling is expected to be dominant in the strong-gravity regions such as near blackholes or the early Universe. With better instruments planned shortly, electromagnetic fields are an important source of astrophysical observations to test general relativity in strong gravity regimes. However, to precisely test general relativity in strong gravity using electromagnetic fields, it is imperative to obtain constraints on the non-minimal coupling parameter to electromagnetic fields. As a step in this direction, we calculate the deflection angle of non-minimally coupled electromagnetic fields in the vicinity of a dynamical, sphericall...

ABSTRACT. A method for producing a large class of force-free electromagnetic field solutions in curved spacetime is presented. Analytic examples in flat spacetime are given. All the solutions start with a null electromagnetic free-field solution with special properties. Then, a transformation of the null free-field solution produces a solution to the force-free problem. Examples based on the Hopf-Ra ada electromagnetic knot are presented. All of the solutions considered have the property that both invariants of the Faraday tensor are zero. ...
