Could one use magnets to create friction and thrust

AI Thread Summary
Using magnets to create friction and thrust in a motor setup is conceptually discussed, but the feasibility is questioned. The proposed design involves a pendulum with a magnet and a stationary magnet, but the mechanics of attaching an oscillating pendulum to a non-oscillating motor are unclear. Participants express confusion over the description and the potential for levitation. General consensus indicates that while magnets can create levitation, the specific design presented is not viable. Overall, the idea lacks clarity and practicality in its execution.

if I had a motor with a pendulum and a magnet at the end of it, and attached to this motor was a frame holding a another magnet that is close enough to the pendulum to exert force on it when it is horizontally positioned would that force make friction with the inside of the motor creating thrust in the opposite direction when the motor is spinning? to make the whole thing levetate

I can't follow your description without a diagram. How do you attach a pendulum (which oscillates) to a motor (which doesn't)?

Would it levitate? No.

Me neither. But in general, you can make things levitate with magnets:

OP said "the whole thing" :-)
 
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...
