    Link: Does It Work? The Wireless Homopolar Motor - I don`t know what he`s trying to say, but the magnet moving on its own is surely a cool thing.

    And to think I was proud because I knew how to build a wireless heteropolar motor.

    The same thing will happen if you put a compass in the center. The compass needle will spin.

    I do not know what is suppose to power this thing, but I am going with a motor under the table. Age old con. Most perpetual motion machines work that way.

    Ok been looking up homopolar motors, and am calling BS on this. For 2 reasons, no copper wire is involved, all working ones I saw had copper wire and a magnet. Facilitating a current, that formed the magnetic field, that drove the motor. The other is this. He used both 9volt and AA these have their contacts positioned differently, so they would not work together. The motor is under the table. It did give me an excuse to look up homopolar motors, that was kinda cool.

    And if you don`t have enough AA batteries, just open up a lantern battery. It has 32 of them inside. LOL...

    there is no current in a battery since the circuit is open, therefore there is not magnetic field being created.

    I think this might actually be real. SistaRose your correct that it requires copper but only if the core is iron. The core in this case is a magnet or magnetite. The electro-magnetic field set up by the magnet might interact on the positive and negative electric fields set up by the 9Volt`s, the AA`s might just keep it in position and boost the electro-magnetic field.

    The current might be created as the magnetic field rotates relative to the electric fields pulling electrons and causing a current and creating a electro-magnetic field.

    Amazing! At 1:03 it completely vanishes!

    (And what the hell does a mirror and "lans" have to do with it??)

    I`m a physics major in university and I cannot see how that would possibly work. If someone wants to explain how an open battery with no flowing current creates a magnetic field, and how optics have anything to do with this, then please do. Until then, I`m saying it`s a spinning magnet under the table.

    @Sathon: Thats why motor construction isn`t left to physicists, let the engineer take over.

    You all seem to be under the impression that a motor needs to have wire coils to function. It does not, the wires just massively increase the efficiency of the motor, note how he needs a ridiculous number of batteries to get the magnet to turn slowly. A motor works (basically) be intersecting electrical and magnetic field at right angles to each other in a circular arrangement, then letting the Lorentz force take it`s cause. Here he has set up an electric field using the batteries and then set a magnet at right angles inside the field which then keeps spinning after he gives it a little push (presumably the force isn`t great enough to over come inertia). The power for the motor is coming from the batteries, which will eventually run out of power if you leave this running long enough. The purpose of the mirror and lens is to act a a home made very low friction bearing.

    Any quest

    obviously fake, but the truth is that every electromagnetic motor has no wires (between the stator and the rotor)

    they need to teach the laws of thermodynamics in elementary school so people stop attempting these videos.

    @Sathon how optics have anything to do with this

    nothing their just smooth and redue friction that all

    As much as I appreciate a healthy level of skepticism, people instead of being skeptics are just crying "Fake!" with the same fearful tone people used to cry "Witch!".

    This isn`t fake. I have the relevant expertise in motors and wireless power to know this isn`t fake. Stop thinking you look intelligent by calling anything you don`t understand fake, it makes you look stupid.
