A Overview of How MagLev Technology Works Essay

Why Maglev . . . MagLev technology is entirely different from any form of transportation in operation today, but the basic principles that lie at the foundation are not beyond the understanding of the beginning electricity and magnetism student. It is in the application of these principles to design and optimize an actual train that things get hairy. The basic idea has been researched since the mid-sixties, but it is only now that economically feasible prototypes are being built and governments are seriously looking towards magnets to propel us into the next century. Leading the race is Germany. Their design, the Transrapid 07, is ready for commercial production. It utilizes conventional electromagnets and forces of attraction to levitate the train. A good web site to find out more about German plans for their design is httptransrapid.simplenet.comindex-e.htm The Japanese are investigating an entirely different design involving superconducting magnets to generate huge repulsive forces which levitate the train. However, their MLU002N is still in experimental stages. For more information, check out httpwww.rtri.or.jprdmaglevE.html With a little stretching, the average physics student should be able to comprehend the principles of magnetic levitation and propulsion through synchronous linear motors. To facilitate the process of understanding this complex material, we suggest that the student go through this web site in order. Make sure you understand the basic physics before moving on to the page which applies these principles to magnetically levitated vehicles. Moving Charge -- Magnetic Field Intro We know from experiment that a moving charge exerts a force on other moving charges we call this effect magnetism. The magnetic force is a field force, meaning that a moving charge sets up a field which in turn exerts a force on other moving charges. The field set up by a given moving charge is found to be perpendicular to its velocity, and to decay with distance from the charge First, we will...

Character Analysis of Basil Hallward in The Picture of Dorian Gray, a Novel by Oscar Wilde Essay

The main character in The Picture of Dorian Gray, Dorian, is a man too easily influenced by his surroundings. He is quoted as saying, Basil Hallward is what I think I am Lord Henry is what the world thinks me Dorian is what I would like to bein other ages, perhaps (Wilde). This comparison falls in line with the moral of the story because Dorian is stuck with eternal youth and beauty even though he has a wicked soul. This causes different views of him by people who observe his daily life. Dorian is a sponge throughout the novel that absorbs everything and allows it to shape his personality, morals, and actions. Dorian Gray takes influence from Lord Henry, Basil Hallward, and the culture of society during which the novel was written. Lord Henry is the epitome of a wealthy, hedonistic gentleman seeking only pleasure, with little regard to cost or consequence. Lord Henry Wotton outwardly propounds hedonism, but it is his extreme egotism that drives him to manipulate both Basil Hallward a

Religious Symbolism in The Blessed Damozel, a Poem by Dante Gabriel Rossetti Essay

Dante Gabriel Rossettis poem The Blessed Damozel is full of religious symbolism. There is talk of saints, and the poem itself takes place in heaven. But underneath the religious symbolism is a deep sensuality, that makes one wonder if the white rose of Marys gift referred to in line nine is the gift of Mary the Virgin, or the somewhat less virginal Mary Magdalene. While the Damozel is in heaven, her appearance in heaven, her behaviors in life, and what happens when she and her lover are reunited suggest some less than virginal dealings, yet the damozel is blessed and resides in heaven. Rossetti was the child of liberals kicked out of Italy a heavily catholic country for their extreme political views. While Rossetti himself was not political, he may have espoused similar views regarding politics and religion as his parents. In the poem The Blessed Damozel, Rossetti was given the chance to essentially create his own heaven. Most everything he wrote seems to show that Rossetti espoused

An Analysis of the Character of Chichikov in the Poem, Dead Souls by Nikolai Gogol Essay

Dead Souls takes place in the Russia of the late 1800s, where, unlike in America, one must be born into a prosperous family in order to have opportunities. The main character, Chichikov, is clever enough to develop a scheme in which he can rise from being a petty clerk to a respected landowner. In order to do this, Chichikov moves into a new town, pretending to already be a landowner, and begins a quest to buy the names of dead serfs who have not yet been officially reported dead. Each person that Chichkov presents this offer to has a different reaction, starting with the shy and introverted Manilov. Though he does not understand Chichikov's need for the names of these dead serfs, Manilov is a character that is so desperate for company that it does not take any effort to trick him into selling his dead souls cheaply. However, as Chichikov continues his journey, he starts to deal with more clever landowners who become suspicious of his scheme. Chichikov finds that the townsmen know
