Principle

Turning a coil in the magnetic field generates voltage on its ends (induced voltage). After each half rotation of the coil the voltage changes its sign. If just at this moment the polarity of the coil winding is reversed with the help of a so-called collector, then DC voltage is generated. A light bulb can be operated with the electrical energy generated.

Benefits

  • Demonstrative experiment due to large instruments 
  • Easy and sturdy setup
