When I try & pass some earth magnets through a looped coil(coil is atached to a battery)…the coil moves but,?
when I move a nail that has a coil of wire wrapped around it & is also attached to a battery, the original looped coil, nothing happens?
Does an electro-magnet(the nail/wire) not have an effect?
what else can I do for this experiment?
