First-time wireless device used to make non-magnetic material magnetic.
Theoretically, it's not difficult to make a magnetic effect in non-magnetic material is not difficult. The system that makes the magnetic effect should only turn all atoms in the targeted object in the same way. That means the north pole of the atoms must turn in the same direction. And then the magnets can get effect to those atoms.
The reason why some materials are magnetic and some are not magnetic is that there is entropy in non-magnetic materials. The entropy causes atoms to be topsy-turvy in the non-magnetic materials. And the order of atoms makes iron magnetic. The electron shells of iron atoms can create spins or magnetic domes. Those things can form magnetic dipoles. And then the magnetic dipoles make possible the magnetic effect of the iron.

Theoretically is possible to make those magnetic dipoles into other materials. However other materials require outside effects to form magnetic dipoles in their structures. There are tested things like X-rays and powerful magnetic fields that can turn things like plastics to react with magnets. If that kind of radiation is possible to create that thing turns tractor rays true. The fact is that the UFO-scale tractor-ray is not developed yet. But this wireless device that brought magnetic effect to non-magnetic material is a step in that direction.
Researchers at the University of Barcelona used Cobalt Nitride for the first experiments for creating non-magnetic material that reacts to magnets. In those tests, researchers used platinum electrodes. In that case, researchers used wireless devices to make that thing. This test proved that non-magnetic materials can turn to react magnets.
