We use the Ernst-Schwarzschild solution for a black hole immersed in a uniform magnetic field to estimate corrections to the bending angle and time delay due-to presence of weak magnetic fields in galaxies and between galaxies, and also due-to influence of strong magnetic field near supermassive black holes. The magnetic field creates a kind of confinement in space, that leads to increasing of the bending angle and time delay for a ray of light propagating in the equatorial plane.

  1. Horizon-Evanescent Scalar Clouds from Coupled Rotation and Magnetic Fields around Black Holes

    gr-qc 2026-06 unverdicted novelty 7.0

    Magnetic fields around Kerr-Bertotti-Robinson black holes quench superradiant instability, enabling both classical synchronized scalar clouds and a new class of horizon-decaying stationary clouds.

  2. Horizon-Evanescent Scalar Clouds from Coupled Rotation and Magnetic Fields around Black Holes

    gr-qc 2026-06 conditional novelty 7.0

    Coupled rotation and magnetic fields produce horizon-evanescent Type-II scalar clouds on Kerr-Bertotti-Robinson black holes by rendering the near-horizon wavenumber imaginary below the usual synchronization frequency.
