The HIDDEN Magnets in Your Phone ft. MKBHD

Light is also an electromagnetic wave. So in principle this magnetic paper should respond to the incident light. Now considering practical limitations like average response time of the magnetic paper, magnetic field strength of the light etc, I would say that the paper could at least respond to high intensity radio waves etc.


Another thing, If there are just tiny nickel pieces inside the paper, they should also respond to electric fields. Can you check if that is the case ?
