Dating back to 4000 BC in Egypt, drums are the oldest known instrument in the world. Not only have people been using drums for a long time, but Macaque monkeys also use drumming to show dominance and communicate. Drums have been used all over the world as a means of communication or a way to create music. People who play the drums heavily rely on the physics behind them, but many people never truly realize how much newton's third law takes place in their activity. When a person plays drums, to simply put it, they are just hitting drums in different ways at different times. The main thing they are doing is bouncing a stick, a hand, a mallet or something similar off of a drum. Without being able to bounce something off the drum, drumming would be drastically different, or even non-existent in this day and age.

Both the sticks, mallets, hands, etc., and the makeup of the drum itself have major roles in the physics of drumming. For example, without Newton's Third Law, the drumstick would never bounce off the drum, leaving drums having a dull and bland smacking noise. Newton's Third Law states that every action has an equal and opposite reaction. The action would be the sticks hitting the drum, and the equal and opposite reaction are the sticks bouncing off the drum. As the sticks push against the drumhead, the drumhead also pushes against the sticks with an equal and opposite force, leaving the drum resonating with sound and the sticks back up in the air. This is possible because of the tension in the circular membrane of the drumhead. The tension makes it easier for the sticks to apply more force to the drumhead and make a louder sound while being pushed back up to hit again. Different drums also have different ways they need to be hit. For example, the snare drum needs to be hit in the center, whereas the timpani drum needs to be hit near the sides.
The ideal circular membrane has a fundamental frequency of ƒ1=0.765((√ T/σ)/D), where ƒ = frequency, T = membrane tension, σ = mass per unit, and D = the diameter of membrane. With this ideal frequency, it is easiest and most efficient to hit the drumstick off of the drum. Leading back to Newton's Third Law, when it is most efficient to hit the drumstick off of the drumhead the forces of physics網上補習 the sticks and the drum are completely equal and the drum leaves a resonating sound as the stick goes back up the be used to hit the drum again.
The Hans Coler Stromerzeuger was the second of this German inventor's magnetic motor devices that was capable of generating electricity on its own. So much so, that the German navy and even British intelligence were known to be highly interested in it. Keep reading to find out more about it and how it worked and how you could have your own Stromerzeuger at home generating power for you and your family's needs - for free.
The Stromerzeuger
Meaning literally "power generator", the Stromerzeuger had its own unique features (like all magnetic generators) and consisted of two electrical circuits. It used magnets and coils and the power was used to light up a bank of lights.
This device was a great source of interest to the military. It was verified by two professors but the official story is that it was destroyed by Allied bombing in 1945.
How does it work? Most people today think that Coler did not really understand how it worked. Explanations can be found in "zero point", a fringe area of physics. However, Coler's explanation relied on an electron not being just a particle but also a magnetic south pole. Even combining conventional physics with what we know about zero point, this concept cannot be proven or even understood easily.
Zero Point
The real explanation for this motor, Coler's other motors, and all other types of magnetic motor is that they operate in an area of physics previously mentioned, "zero point". Though much study and research was done in this area approximately 100 years ago, nearly all of it was suppressed by commercial interests until recently.
These days, with the advantage of the internet, it is too difficult to achieve a blanket ban on information. People can talk freely about zero point and nobody can do anything about it except that point out that conventional physics has no explanation for how it works. All the while, governments around the world are locked in a race to perfect it as quickly as possible because zero point could revolutionise propulsion and give a country a huge military advantage.
Make Your Own Stromerzeuger?
Could you make your own? Indeed you could, or any other type of magnetic generator. Coler's inventions were not unique - he and many others have made their own versions of magnetic generators over the years and each working slightly differently and giving different advantages and disadvantages over each other.
Ultimately, all of them are similar at their core. They convert the power and force of magnetism and gravitation into motion which can then be converted into electricity in a way not dissimilar to a water wheel, for example. They consist of little more than magnets, a rotor and some basic electrical wiring.
If you want to make one yourself in order to power your home then I strongly advise investing in a good, reliable set of plans that are guaranteed to save you the headaches that pioneers like Cole experienced. With a good set of plans that will probably cost 50 bucks or so, you could quit paying for your electricity within a matter of days rather than tinkering around for months on end, trying to save face in the process.
