for a science fair project one year I took a multi strand electric wire, striped the insulation from it and spaced out the individual strands (with regular clear tape), taping them down to a sheet of waxed paper so they looked like a sheet of copper strands, then I took a bunch of lego magnets and taped them in a row to a ruler, alternating +-+-+- then with both ends of the wire connected to a flash light bulb (one end ground one end positive doesn’t matter what end is what) by rubbing the ruler over the “sheet” of wire, the light bulb would glow dimly
short answer: its possible. take a loop of wire connected to a light bulb. now take a magnet and constantly spin it or make it move constantly. This effect will induce a current through your loop that is not touching the magnet.
why does this work?
long answer:
the change in magnetic flux induces an EMF in the loop which starts a current. the current makes the light bulb light up. This only works when the magnetic flux is changing, aka when your moving the magnet around.
believe it or not, most electricity is produced this way commercially. having giant magnets(turn by turbines in a dam) to induce currents.
