    I don`t think it would work, but I could be wrong. I don`t know much about electro-magnetic fields, but I didn`t think simply passing a current through a wire created a magnetic field. At least not one strong enough to pick up anything. I mean, if that were the case, I shouldn`t have to worry about losing sockets in my engine compartment because the magnetic field should keep them from going anywhere I don`t intend them to go.

    I always thought you made an electromagnet by wrapping a piece of iron (i.e.- a nail) with a copper coil and then making a complete electric circuit through it. In other words, the wire would have to be touching the cathode and the anode on the battery.

    This would not have worked with a nail... it has to be a screw. Why? Because you can pick a screw up with a wire by catching a thread. No circuit was formed. Sorry NyQ, it`s not an electromagnet... it`s a trick.

    it didnt say it was an electromagnet...reread, genius. what i said was that a current through a wire creates a magnetic field. i also qualified my statement with the fact that there need to be certain characteristics.

    but the fact remains: ANY electrical current creates a magnetic field.

    I didnt speak to the strength of the field at all

    lerber3 is correct, this is a trick since air is an excellent insulator. Try this, put your hand near an electric outlet. Notice how you don`t get shocked? You`ve now performed a science experiment proving the insulating properties of air.

    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.

    This could not be an electro-magnet because the circuit is open and there is no currant. No currant = no magnetic field. There is however, an electric field between the batterie cap and the screw tip.

    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.

    ... Reminiscent of "putting cabbage in water= magnetic water" or that thing that stands the spoon on end... Because no complete circuit actually formed: this is not an electromagnet. Whether other things were magnetized...

    Note how at the beginning of attmepting this experiment, the wire slips. Oh yeah, that`s DEFINITELY an eletric current. -.-`

    I`ll agree with the fact that this is a fake, but the statement about air as an insulator is moronic. Air is a great insulator for electricity, but a magnetic field isn`t electricity, and doesn`t even need a medium to propagate.
    Oh, and the coil around the screw thing works without the screw, as an electromagnet is a current passing through a coil, but the screw increases the power of the field.
    And yes, any wire transmitting current makes an EM field, but in order for it to have magnetic poles, it needs to be in a coil.
    Also, the levitation distance is impossible to keep steady when you move the magnet like that, so there`s a thread.
    Good news is, you can make an electromagnet with some wire and a battery anyways :P.

    did anyone else notice that when he moved the battery away from the screw, it neither came closer to the battery nor the ground? also there was no complete circuit, so it is fake.

    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...

    An electromagnet does involve a closed circuit making loops around a metal object. That wouldn`t have worked. The magnetic field created by the wire isn`t strong enough to hold a screw in the air. Just wrap the wire around the screw as much as possible then attach it to both ends of the battery and see if it attracts another screw.

    If it was an elctro-magnet, The screw would come up to the battery and stay there. It floating shows that it`s not :)

    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)

    Guys...this is fake. The stripped wire is just picking up the screw by a thread. The circuit is open, no electricity flows through, no magnetic field.

    I teach Mad Science to grade school kids and we have an electric magnet along this line.. You need metal, battery and +&- wire so this method shound work
