Optical trapping is a powerful tool for studying fundamental physics on the nanoscale as described by electric field-based light-matter interactions. However, the range of capabilities would be greatly enhanced by understanding its magnetic counterpart. Our studies provide experimental evidence of optical magnetic trapping. In particular, our work identifies new forces in optical trapping of Si nanoparticles stemming from the Photonic Hall Effect. We also discovered optical-driven Brownian engines at the single-particle level whose counterintuitive behavior originates from optical magnetic light-matter interactions. As a result, optical magnetic trapping now offers new opportunities for particle manipulation in optical beams.
