Hum Motor – Flash camera trigger coil powered

A disposable camera trigger coil, directly connected to a 6V DC source from a wall adapter. The mains line ripple is my theory of how it works. Rotor is from an old 12V PC fan, just the central metal bearing and the plastic top that has the fridge magnet type innard. The 4 neodymium magnets are arranged all facing North outwards. They stick easily to the side of the rotor, but in this case are superglued on to make sure they don’t move. Fun experiment 🙂
