No you didn`t. This doesn`t work, it`s a scam to see how many people are stupid enough to think it works like that. Looks like there are QUITE a few.
And electricity doesn`t pass through mose objects, but around it. Hence an electromagnetic field (Even your muslces make electromagnetic fields)but I see no circuit (A circuit can be made with air, but not when it`s that weak)
im pretty sure that you would have to wrap the copper wire around the metal, apply electricity, and then touch the metal to the object you wanted to pick up...
The potential difference is only 1.5V so the electric field would be rather low. However, since the tip is very pointy, there would be a field effet at this point that could make the field high enough to result in an observable attractive force.
I tried it, but I did not have the exact same material. I was not able to observe the effet.
Even thow is would there IS an electric (not magnetic) atractive force between the screw tip and the battery, it is probably not stong enough to lift the screw. This is probably BS.
Yes, the screw is being held by the wire on a thread.
To make an electo-magnet, wrap the wire around the screw and connect the ends of the wire to each end of the battery.
but the fact remains: ANY electrical current creates a magnetic field.
I didnt speak to the strength of the field at all
