Abstract

Constant magnetic fields are known to interact with electrically charged particles inducing Lorentz forces that point in a direction perpendicular to the field. However, if the particle is electrically discharged, it is impossible to induce a force using a constant magnetic field. An exotic option is to mimic a magnetic charge on a neutral particle. This false magnetic monopole will interact with the magnetic field just as an electric charge would do with an electric field through the Coulomb interaction. Attempts to generate this magnetic charge have mainly relied on quasiparticles generated using condensed matter spin ice networks. In this work we present another option based on neutral magneto-optical particles illuminated by a spinning monochromatic light field. We will analyze the behavior of these particles under different isotropic optical configurations, and we will calculate the value of the induced magnetic charge.
