The role of magnetism in memory technology is well-understood, but researchers at the Hebrew University of Jerusalem recently discovered a connection between light and magnetism that could give rise to light-controlled memory.

The magnetic properties of light have historically garnered less attention because of the slower response of magnets compared with the rapid behavior of light radiation.

The research shows that the magnetic component of a rapidly oscillating light wave possesses the ability to control magnets, redefining principal physical properties. The discovery is contrary to conventional thinking because it focuses on the magnetic aspect of light.
