Maglev Train for Electricity and Magnetism- myassignmenthelp

Question: Discuss about theMaglev Train for Electricity and Magnetism. Answer: Outline Structure Maglev is an abbreviation for the magnetic levitation, which is a process and transportation method where it describes the movement of a suspended object without any other support but through the use of magnetic forces. In transport, maglev train has been able to embrace this technology and ensuring that the vessels are not in contact with the ground (Lecture, 2002). The magnetic forces in this technology are used in order to counteract the effects, which are brought about, by the gravitational acceleration or any other accelerations which may bring the object movement. In the maglev, the major key subjects, which are able to get involved include the lifting forces and the stability measures (Mestel, 2006). The lifting forces in this mechanism are able to provide the upward force, which is used to counteract the gravitational force or other downward forces. Moreover, the stability issue is able to ensure that the whole system do not slid or flip out of the configuration. In these tra ins, the magnet is able to provide the lifting force and the repulsion force which is required for the vessel to move. The main aim of this technology in the trains is to ensure that the frictional forces is reduced to zero and therefore enhancing the increase of the speed movement (STR, 2003). Moreover, through this technology, the maglev trains are able to move smoothly and quietly as compared to the mass transit systems and trains. In addition, another key area, which this technology is to focus on the energy consumption and the technology, enhances the energy efficiency. In terms of the trains speed, the maglev trains are able to hold the highest speed of the trains. Laws and Theories The maglev technology in the train is able to use the forces of attraction of the magnets to enhance the movement of the trains. The maglev rain is able to apply the magnetic forces to ensure that it is able to maintain its speed and stability. The maglev technology ensures that the train is suspended above another object (STR, 2003). The laws of magnetic attraction and reputation are abler to apply in ensuring that the technology is able to achieve its objectives. Moreover, the interaction of the gravitational forces and the magnetic forces are other key rules which is applied on this technology. The maglev train has to be maintained on the suspended position and ensure that it is able to move at that position. The magnetic forces have to control the downward pull of the gravitational forces (Mestel, 2006). The repulsion between the magnetic field and diamagnetic substance is able to enhance the ole of this technology. Moreover, the attraction between the unlike poles of the magnet must be maintained to ensure that the train does not move much higher. This balance is in maintaining the position and stability of the maglev train. Through the electromagnetic attraction, the sensors are able to enhance the reduction of the frictional force since the train is suspended (Thompson, 2013). Moreover, the levitation force is another rule which the technology is able to embrace. This ensures that the train is able to attain it maximum speed and able to move forward. Lastly, the linear synchronous motor (LSM) is able to ensure that the maglev technology is able to move and attain the required speed. Other technology and rules in this technology is the Linear Induction Motor (LIM) and reluctance motor. Description of the Way Laws and Theories Work The device is able to ensure constant level of the train through the magnetic force attraction and repulsion. In addition, one of the force, which is critical in the maglev train, is the levitating force (Lecture, 2002). This force ensures that the train is able to move forward and attain the specified speed of design. There are three different levitating systems which could be applied on this technology. These include EDS system, EMS system and INDUCTRACK systems (Mestel, 2006). The eddy currents are able to play a key role in ensuring that the levitation of the maglev train is achieved. At different speeds, the induction poles are able to behave differently. The EDS is usually in both the train and the rail, which is able to offer the repulsive force leading to navigation. The EMS, which is a shirt form of the magnetic suspension, helps to employ the magnetic attractions. Discussion of Issues The speed issues have been arising each time. The train is modified to increase the speed limits with japan holding the fastest maglev train followed by china and formula I racing car. The increase of the speed is able to affect the stability, therefore needing proper consideration. Stability is another key issue which is raised (Thompson, 2013). The speed is able to lower the COG and therefore placing the risk of train failing. A small displacement will be able to change the stability equilibrium which may lead to accidents. The increase in distance is able to lower the strength of magnetic attractions which is a key issue in the maglev train. The strength of the magnet is able to the stability and the security of the train. This is a key issue which is required in the application to ensure that the train is safer and able to maintain the safety requirements. Impact of Maglev Train The achievement of high transportation speed is one of the positive impact, which the maglev train has been able to have. The high acceleration motors are usually used top, enhance the linear induction design of the maglev train. In addition, efficiency is another key impact which this technology is able to embrace (Rote, and Yigang, 2002). The same magnet, which is used on board on the train to supply the lifting force, can be used to guide or even offer separating guidance of the magnets. This technology is able to ensure that high speed is achieved at the most economical measure. This is a key impact, which is able to enhance the speed of the train. The train speed is able to enhance the movement between different points. References Ignorance = Maglev = Bliss For 150 years scientists believed that stable magnetic levitation was impossible.
