The new observations about magnetism and magnetic field interaction with light can make a new era for precise mass memories and data transmission. The thing that connects light and magnetic field is this: they both are electromagnetic wave movements. But their wavelength is different.
Radio waves have long wavelengths. And the visible light has a shorter wavelength. The X- and gamma-rays have the shortest known wavelengths. It's theoretically possible that light can transfer information straight into the radio waves. This process requires ultimate accuracy. The lightwave must interact with the radio wave long time. That it can transfer its wave mode into that much longer wave movement.
In the same way, it's theoretically possible that gravitational waves can transfer information straight to radio or light waves. The problem is that this process requires that information can travel between different wavelengths. But if that information transfer is possible someday, it would open new visions for space research and communication.

The wavelength determines the type of electromagnetic radiation in the electromagnetic spectrum. Interaction between the magnetic field and light means. That information can transfer between those wave movements. And that thing makes it possible to transport data between magnetic fields and photons.
Light interacts with the environment like water. When photons travel through magnetic or electromagnetic fields. They act like a thermal pump. That means photons can move energy in and out of the magnetic field. That energy impact changes the shape of the magnetic field. Same way when a photon hits an electron, it transfers energy into it. That ability can used to transport information to quantum computers.
When light travels near the magnetic metals it can pull energy out from its route. With it. So the light beam can transport an electromagnetic field away from the structure. And then the electromagnetic energy from the magnetic material travels into the position where light pushes the electromagnetic field with it.
Or even if light cannot interact with the magnetic field or magnetic wave movements it certainly can interact with electrons. When a light beam hits electrons it can push them into another direction. The system can be used in the new type of optical electronics.
The light can also increase the temperature of the magnets. That thing allows them to adjust their power. The reason why warm magnets have more power than cols magnets is that in warm magnets there is more space between atoms. So atoms can turn more easily than in the cases they are in the cold objects.
