I learned as a Cub Scout that if you coiled wire around a screwdriver and attached the wire to a 6 volt battery, the screw driver or nail would become magnetized.
It would appear that the numerous Indian mechanics who have created various similar constant running generators have learned to reverse that process and to use magnets in a process of generating continuous electricity.
but the magnet must MOVE across wires to generate energy - what powers the movement? It’s what a generator does. All of these are scams. Think about it. If it worked we’d have free energy. It isn’t hard to prove...if it worked nothing could stop everyone from doing it.
