Definition: Photomagnetic refers to a phenomenon in which light is emitted from an object and returns as a magnetic field. This process is used in various fields, including electronics, nanotechnology, and bioengineering. The term was coined by physicist William J. Dyer in 1962. It's important to note that while photomagnets can be observed through the use of light sources, they are not typically used for practical purposes due to their limited size and low energy output.
