The direct current generator (DEMO)
Article No: P1433869
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. Particularly comprehensible and didactically prepared description of experiments (reference to everyday life, etc.) incl. protocol questions Future-oriented teaching: Integration into digital science lessons Increased motivation among students through use of the intuitive measureAPP Increased media literacy Demonstrative experiment due to large instruments Easy and sturdy setup
