Electromagnetic motor using battery and magnet?

AI Thread Summary
The discussion centers on the mechanics of an electromagnetic motor that utilizes both a battery and magnets. Participants question the validity of the motor's operation, considering whether it is a legitimate concept or a hoax. The role of Ampere's force is debated, with some suggesting it may not apply in this context. The configuration of the current flow and magnetic field is analyzed, particularly how a perpendicular orientation can generate torque. Overall, the conversation seeks to clarify the principles behind the motor's functionality.

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.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
