I am not a physicist, but I know the first law of thermodynamic (conversation of energy), and I have connected this with an idea that came to my mind some time ago to create perpetual motion machine which impossible according to the first law of thermodynamic.
This spinning wheel is made of ferromagnetic material ,So a force will be applied on the wheel causing a torque ,If we put this in place with no air ,and these are permanent magnets so they are going to apply a force permanently,and the atoms in the ferromagnetic material will not be aligned because the permanent are in opposite directions so how would this wheel stop acceleration ?
