Working Attraction Magnet Motor on Youtube!?

[hansvonlieven]

G'day all,

I will probably get shouted down for saying this, but I have severe doubts as to the authenticity of this device. Having studied the video very closely I noticed the behaviour of the bracket that holds the magnets is not as one would expect.

It apparently just sits on the board. The ease with which the operator moves it around suggests it is not fastened.

Now there are two ways in which the device might function, if the screws are magnetised repulsion can be used, if they are not only attraction will work.

There must be a force between the screws and the magnets that propels the device. This to me would seem to require that the bracket is rigidly fixed to the base, otherwise it will just get pushed away or attracted to the screws and stick. The weight of the bracket and the magnets is insufficient to hold it in place, especially on the smooth surface of the base board.

I am always weary when an old disk drive is used for a turntable, as it contains a small motor.

I hope I am wrong, but I don't think so.

Hi Hans,
if you watch closely he has screwed the magnet holder stand onto his table
plate and can only move it right or left.

There is nothing wrong with being a skeptic, I too have some unanswered questions.
  When he lifts the board, the bracket with the magnets does not move at all.  If it was fake you would expect it to slide backwards.  At the very beginning there is a quick overhead shot where you can see what might be some magnets places inside the short end of the bracket were it contacts the board.
Of course this doesn't make sense because the board does not appear to be metal.  I hope the creator will step forward to give us some of the technical details.
  I have all the supplies in order to build a replica, I will try to report my results soon.

Sorry Stefan,

There is indeed a screw there that holds it to the board, I missed this earlier, but it does not hold much, he moves the bracket with too much ease and does not fasten it after he moves it in place. My earlier comments still stand.

Me too Han?s , the audio seems to be faked to me.
Notice the strong click sounds (one out of sync too I think?) when he touches the screw driver to the screws.
The sub titles seem strange too.
It could maybe be a can of compressed air spinning it with fake audio.
