Title: Magnetic Perpetual Motion

Impressed by Norman's animation idea.

I don't see what the iron channel is for. I guess it would rather act as a brake on the rolling magnet, regardless of direction. Then, yes, the fixed magnet will push away the roller, but regardless of if the roller is still getting closer or is already being pushed away, the force is the same. So this acts more llike some rubber foam that is sqeezed.


Due to friction losses, the roller will become to rest in the middle after bouncing several times back and forth.


Or maybe I misunderstood the concept/idea?

Iron channel is used to cut off the flux when magnet moves down the plane so that it will not experience repelling force from fixed magnet while moving towards it.   Iron channel will not act as any brake since it has flat uniform surface and magnet will move easily parallel to a uniform shielding plate.  Sticky point will be only at the edge (end) of the channel. Magnet can overcome this sticky point due to its momentum gained while rolling down the plane.
 
Things will happen as you said above only if you remove the iron channel. 
 
Rolling magnet has to be placed in a slot exactly at the center of the channel.  If not force acting on one side of the magnet will be more which may act as brake as you said.
 
This experiment is based on  principle of magnetic flux "ON" & "OFF"  with respect to another repelling magnet.

My experience is, when you try to cut off the flux with iron like that, it will have the same impact, regardless whether the roller is rolling towards or away from the fixed pm. But I could be wrong. At least this seems to be easy to build. Could the roller also be a pendulum instead?

You can make it as pendulum also.   This experiment looks simple, building it also easy but not so easy to make it work because cutting off flux 100% is very difficult to achieve. You have to keep the faces of channel very close to the magnet and magnet should move without touching the iron. It requires some perfect and accurate fabrication work.
