1. Phonon in Dinamo <br />A. Muqoddimah In the technological dynamo, a factor which is often considered the scientists is the large Lorentz force sistem.In fact, there is an important energy in the process of rotation of the armature coil is phonon energy. B. Explanation Phonon role in setting the armature acceleration and top speed adds an armature coil as well as the Lorentz force, but the 'quantity' is inversely proportional to the Lorentz force. When the bottleneck in the system the coil is smaller than the outer barrier system, the Lorentz force in the system is greater than the outside of the system according to the formula: (Formula) So the Lorentz energy in sistempun greater than outside the system, according to the formula: (Formula) As with the phonon energy because when the system resistance is smaller then the distance was smaller interaction energies so that the phonon energy resulting in a smaller system than outside the system. With two of these symptoms then there is the velocity of the coil with a certain acceleration and will reach maximum speed in accordance with the amount of electrical power that goes into the coil. So it is less appropriate if the velocity of the coil is only caused by the Lorentz force, because if so then it should direct spindle rotation speed of zero to 'top speed' without gradually.but fact experimentally proved that the speed of the coil stages with a certain acceleration in accordance with the number of coil windings. Therefore, in addition to Lorentz force, the velocity of the armature coil is influenced also by the phonon, so that the length of time the current flows and the resulting magnetic field induced Lorentz force will 'react' gradually with phonon outside the coil system. So the Lorentz force will act as a driving force that leads to the central coil phonon maksiamal outside the coil system whose effects such as towing style coil with a distance certain.as a result total generated energy of motion is a combination of two factors which are of the form of electrical resistance in the system and from outside the system distance of the interaction energy between elektron.Sesuai formula: (Formula) C. Conclusion Therefore, it can also be understood that the armature coil is 'overheated' turnaround did not happen because the phonon energy in and outside the coil system has been balanced so that the left is the Lorentz force which can not 'do' the movement of the coil so that actually damage the coils.
