Electromagnetic motor using battery and magnet?

  1. Dec 22, 2012 #1
    I've been wondering how does this motor work (if it is not hoax in the first place)

    I was thinking about Ampere's force but apparently it doesn't really have an affect here. Any ideas?

    You have a radial current flow (moving charges) and a magnetic field perpendicular to that.

    How can the magnetic field be perpendicular to the current flow?

    As far as I can see, the magnetic field is vertical (or at least it has a vertical component), while current flow is horizontal. In particular, the radial component of the current flow in the vertical component of the magnetic field will give a torque.
