For the last couple of years people have been concerned about the waste that has come out of cars, trains planes etc. There are some solutions; electric cars can get there energy from electricity, and the electricity can come from the Sun or Hydroelectric Plants to make the energy renewable. Another solution is vegetable oil gas, for it can be grown and is natural too. But there is one solution that can come from renewable sources, and eliminates friction. This is magnetic levitation or maglev for short. Maglev trains can do many of things that benefits society, including faster transportation speeds. Maglev trains can do many good things, and it all started centuries ago. History Magnetic levitation uses magnets with the same charge that repel each other to make one of the magnets float. This is the basic concept that John Mitchell came up with in 1750. He saw that the repulsive force with two magnets with the same charge. Centuries later there has been ideas that have been talked about, like when Hermann Kemper got a patent for maglev trains. But later in 1966 did the concept be used in a more modern way. James Powell and Gordon Danby proposed the first practical system of magnetic levitation. They proposed using superconducting magnets on moving vehicles to induce currents on a guideway, using aluminum loops. This would make the moving vehicles stabilized vertically and laterally. From 1970 to 1975 the first maglev train and track was being built. In Japan in 1975 the first test of the maglev train took place. This was the dawn of a new generation of transportation that could be elaborated in many ways in the future. Superconductors This new generation of transportation came right out of science fiction. As countries... ... middle of paper ... ...g payloads into space since it can be magnetically launched, or can ship goods faster across countries. All in all, hopefully maglev trains are the beginning of a new age of technology. Our Model The first idea and the most basic idea for our model is to have a track with negative magnets on the bottom. On the sides of the tracks there would also be negative magnets to keep the train level. This idea had no means of propulsion. The train that we make out of a piece of Balsu wood had negative magnets on the bottom and left and right side. But all the magnets had a positive side too, so when we placed the train in the track, the train was getting pulled to one side or another. In this case the attractive forces of magnets outward the repulsive forces. To conclude this idea just didn't work, but it was a great starting point for our mini model of a maglev train.
The strategy behind the high-speed railway system would be to relieve highway congestion, air traffic congestion, and help reduce the necessity of expansion of highways and air systems (which is limited due to the inability to build new air space). Also, with this type of system (this system works on magnetic levitation), you would have a significant reduction in air pollution that would result as high-speed captures a large portion of the intercity travel market from automobiles and airlines.
Electric traction had numerous advantages over steam railroads. One major advantage was electric locomotive’s ability to pull heavier loads than steam locomotives (Bezilla, 30-31). One statement from electrical manufacturers’ stated that an electric locomotive could pull from five times its own weight on a 2% grade, whereas a steam locomotive on the same grade could only pull two times its own weight (Bezilla, 31). In addition to this, the electric motors could sustain higher currents for a short time in order to increase horsepower dramatically; steam engines had no analogous feature (Bezilla, 31). These factors combined allowed for electric locomotives to accelerate more rapidly, even while pulling more weight, than steam locomotives (Bezilla, 31). The electric motor also had less moving parts and thus needed less maintenance than complex steam engines (Bezilla, 31). For example, the Pennsylvania Railroad’s electric locomotives in 1940 were typically running 90% of the time, but the steam locomotives that the electric ones replaced had only ran 69% of the time (Bezilla, 32). The...
The world of Model Train Building has grown greatly with the aid of computers and technology to enhance the fun of building. Technology has long been a part of Model Train building with the adding of lights, bells, and whistles to capture your interest and imagination. But with the latest generation of building comes the influx of technology and the computer. The computer brings along a new breed of builders who plan track layout, buy parts on the Internet, receive updated news, and chat with other enthusiast.
No one person can be credited for the invention of the railroad; rather there are many individuals who contributed to the railways final design. To begin, as far back as the 16th century, Germans were using horse-drawn wagons, pulled along wooden rails. These systems were known as “wagonways” and are grandparents of modern railways. By 1776, wooden rails and wheels had been replaced by iron. Eventually, the wheels became flanged, allowing the wheels to better grip the rails. The major turning point of locomotives was the invention of the steam engine. The steam engine was invented by three different British inventors, over a period of a hundred years; to give only one man the credit would be a crime.
Electromagnetism has a history that dates back over 200 years. The year 1700 was the first demonstration of an electromagnet, yet scientists didn't know much about electromagnetism (Bellis 1). In 1820, scientists had just started to get deep into electromagnets, Hans Oersted discovered that a conductor carrying an electric current was surrounded by a magnetic field (Bellis 2). Hans Oersted discovered this because his compass reacted to a battery when he connected them using wires. That is a big breakthrough because they can now make hypotheses about why the wire with current makes a magnetic field to rearrange the compass direction. In 1873, James Maxwell observed the interaction between positive and negative electrical charges (Brian, Looper 2000). Ben Franklin was the person to figure out that there is a positive and negative charge (Bellis 1). Electromagnetism is the branch of physics that studies the relationship between electricity and magnetism. Without magnetism, electricity couldn't exist, without electricity, magnetism couldn't exist.
The earliest prototypes of self-powered vehicles began in the 1700’s with the first one being built by Nicholas Cugnot, weighing over 8000 pounds and clocking in at a top speed of 2 miles per hour (Bottorff). This large size and slow speed meant that it was impractical as an automobile. Several other prototype vehicles were built in this style by various inventors but were so heavy that they required metal rails to drive on, and so over time they evolved into trains and locomotives (Bottorff). Trains and steam power continued to develop and interest in a self-powered vehicle that didn’t require tracks faded, until the mid-1800’s when new developments in power sources encouraged the development of the automobile.
Levitation is the ability to suspend the laws of gravity that bind us to the earth. It has a lot to do with mind over matter. A person being able to clear his or her minds and think nice, good things enable them to do things that they have never done before. Sounds unheard of, but this has been researched, tested, and even observed by people and scientists from all over the world. Extreme mental concentration is all that is needed.
A brushless DC motor has a permanent magnet or magnets for the armature. The external magnetic field comes from any number of electromagnets that are turned on and off at the correct times by a timing device.
There have been many logical explanations as to how the magnets operate. One explanation for the success of magnetic therapy has been how they utilize the cell’s magnetic field. When a disease invades the body, it disrupts the magnetic fields causing them to become disoriented within the cells. Magnets help realign these fields causing them to be an important factor in counteracting the disease (http://www.healthy.net/hwlibrarynewsletters/update/magnets.htm).
The first time we know about magnets was in 1269, when a soldier named Peter Peregrinus, wrote a letter about everything that was known at that time about a stone called magnetite. It is reported that he was writing this when he was guarding the walls of Lucera, a small town in Italy. It is also reported that, “While people insi...
It is the reason for the great technological movement of the 21st century. Its applications are used on a day-to-day basis. What is this form of energy? It is electricity. Electricity is defined as a form of energy from the existence of charged particles. The charged particles are either positive or negative (protons or electrons). Moreover, through the same principal, the phenomenon of magnetism is also applied on a day-to-day basis. Magnetism is defined as either an attractive or repulsive force between objects due to an electric charge. To thoroughly understand the strength of electricity and magnets, it is vital to first be cognizant of where and when they were discovered.
Rail transportation is a transportation in which for movement of people and goods which from one location to another destination. Rail had been takes the important role in physical and economic development of town and cities in a country and it was developed over the world. Rail transport can be made a property value in a country increase and it must be needs improvement in transportation network expanding (Goldberg, 1970). Thus, the railway services need to be done with continuous improvement and it is important to the rail passengers of the range and quality of facilities and service on stations and trains (Gleave, S. D., 2000). The future development to a public transportation is a key to affect

Hybrid cars are already a well-accepted part of the landscape but many other radical new technologies have been launched or are under development that will revolutionise travel in the cities of the future. Solar-powered buses and trains that obviate the need to build new tracks by straddling existing highways are two of the more eye-catching projects in the
A magnet has an invisible field that forces other objects to respond to its properties. This powerful force, which is referred to as the magnetic field, has particles called electrons that actively shift and move within the field. These electrons constantly revolve around the poles, thereby creating energy that attracts objects. Because of this, a magnet has the ability to draw objects towards itself. This ability, which is called magnetism, is caused by the force field that magnets create through its protons (positive charge) and electrons (negative charge).
