The modern man has got used to use electric energy everywhere. It is hard for us to imagine the absence of electricity, on which most of our full life is based. But have you ever thought about where it comes from? What drives invisible particles, forcing them to work for the benefit of man? The presence of an invisible force that set certain objects in motion was still guessed by the ancient Greeks. However, the real dawn of this topic is only for the period of industrialization of the 19th century. It was then that the famous scientist Michael Faraday discovers the phenomenon of electromagnetic induction, which explains the occurrence of an electric current in a magnetic field environment when the conductor moves in it. Today we suggest that you test this theory empirically. The essence of the experiment is the manufacture of an electromechanical converter based on a DC motor, which will rotate the magnets that are in the frame of the inductor coil.As a result of the excitation of magnetic fields and the appearance of electromagnetic EMF at the output, we obtain an electric current. Interesting experience is also the fact that the voltage values obtained will be greater than the time spent on the engine. But everything is in order.
Materials - Tools
- 3 V DC motor;
- Neodymium magnets, square 10x8 mm;
- Steel bar with a section of 2-3 mm;
- Copper wire in lacquered insulation;
- Plastic pieces;
- 3.7V battery;
- Copper wiring, shrinkable;
Putting together an electromechanical voltage converterMaking a steel bar, we make two small frames stator, we cut the contour with the help of pliers, we cut off the excess, the ends of the coils should also be bent (photo).
C unifying framework for the superglue, and we put in the middle of heat shrinkage. The igniter heats it, and thus we get the isolated core of the coil.
ConclusionIn fairness It is worth noting that electromechanical converters are a thing of the past with the advent of electronic chips and transistors. Today, you can buy ready-made voltage boosting modules, which allow you to get high rates of about 50 V from a standard battery of 3.2 -3.7 V.
