Polarization in a vertical magnetic field for wormholes with different redshift parameters α. Each color represents the observable polarization of the orbits located at r=6M (outer ring) and r=4.5M (inner ring) for a particular wormhole solution with α∈[0,3]. The Schwarzschild black hole polarization is given by a black dotted line as a reference. The angle …
