small AC generator 230 V using a single neodymium sphere 13 mm, a coil without core from a 230 V syncronous motor ( A4 laminators or microwaves turntable motor), a 3 V DC motor (inside electric car toys), and a battery.

From video text:
> test 75 W 230 V bulb ... 2 baterryes 1800 mAh, 3,7 V each
So 7.4V and 1.8AH, 13 Watt Hours of battery.
Rig it to hold a constant distance and thus a constant 230V. If it runs more than 10 minutes before the batteries run flat, you have beaten natural law.
If this is just for fun, yeah, it may amuse folks who don't really know where the power in their lamps comes from. (Steam or dam water spins magnet near coil....)

I tested the small generator using a PWM controller for the 3 V DC motor.
Rotor : 13 mm neodymium sphere
Stator : coil iron -less

PRR, the generators are created in educational purpose. The coil iron - less ( stator) provides a "total capture" of the magnetic flux generated by the 13 mm neodymium sphere.

the 3 V dc motor is spinning the 13 mm neodymium sphere which is staiyng on a metal case (magnetic grip ) connected through a plastic connector to the motor ax. The spherical magnet provides a permanent and constant magnetic flux. The sphere is the rotor of the generator, the coil is the stator.
for example : a small battery 1.2 V + coil + minidrone dc motor + 10 mm neodymium sphere :

It is important to be spherical and the position of the sphere on the metal case is very important (between the magnetic poles).
For example if you will try with a cube magnet (more stronger than the sphere refering to Gauss) on the same setimgs the voltage it will be......half. (i already tried ). shape is important and strenght is importantfor example to light 75 w bulb 230 v I used diferent setups:

coils 40 ohms

3.7 v dc motor
