DC electric generator

 Fidget spinner energy generator ( DC GENERATOR ) :

                      As we know that DC generators produce direct current. Its principle is to convert mechanical energy into electrical energy. A generator that produces current that flows in only one direction is a DC, or direct-current generator.

Dc electric generator out of  a fidget spinner :

The fidget spinner electric DC generator is composed of a small reed switch (the reed switch is an electrical switch operated by an applied magnetic field ) attached on a coil iron-less, 3 neodymium disc magnets, a fidget spinner with iron insertions and a led.

output : DC voltage
