I observed that, when you are making a generator it is very important that, the stator ( the coil) to provide a total capture of the magnetic flux generated by the sphere.

In this video we are using 2 coils of 40 ohms each and a 30 mm diameter neodymium magnet sphere

I have tested the small generator layout  using a PWM controller for the 3 v Dc motor. Rotor : 13 mm diameter neodymium sphere. Coil : iron -less from a syncronous motor 230 V ( inside A4 laminator motor and microwaves turntable). The results :
