Hello mate learn EMF equation a little more
If the rotating motion Cuts a magnetic field only we will have EMF induced
Otherwise there will not be any induction of emf mate SO we will not be able to produce electricity just by rotating a circular disk with a lot of teeth -

Only rotary motion is not sufficient to produce electricity there should be an emf generation which we get in the form of electricity.so my friend the rotating object should be cuts the magnetic field lines then only it induce emf and due to this induced emf we produce electricity.so only rotating objects are not sufficient for it and your disk motion is also not. if i am wrong pls correct me.
