How do Maglev trains use magnet it to function?
Nguyen, Mindy
Physical Science, Period 4
Abstract- Maglev trains, also known as magnetic levitation trains, are public transportation vehicles that are commonly used in Spain, China, and other parts around the world. They are mainly known for using magnetism in order to "levitate" above the tracks. Maglev trains are also known to be remotely quieter than normal trains and emit lower amounts of carbon dioxide.
Purpose- I wanted to find out how Maglev trains were able to use magnets in order to move around subways. The reason I chose this topic is that magnets are seen and used everywhere, whether it's for entertainment purposes or for technical and/or scientific reasons. The Maglev

The main reason that they differentiate is not only the gap in speed rates, but due to the excessive use of magnets that super-conducts and helps it "levitate" During the process of building a Maglev train cart, electromagnets are used. They are made when electric currents flow to coils of metal that's aligned to the track. This is also stated in Faraday's Law of Induction. These electric currents then repel the large magnets that are stored under the train's framework, which is also known as the undercarriage. This process is quite similar to when the North and North poles repel and when the South and South poles …show more content…
This then causes the train to be able to glide super-fast and travel up to 268mph. The Maglev train is able to move quickly due to the lack of friction that would normally slow down a normal train. Instead, the Maglev train rests on a mat of air, having little to no friction. Once the train starts gliding, electricity is not needed for the train to keep moving. Instead as a replacement for fuel, three large magnets are lined up in the bottom of the train, and two magnets in the front and back. The magnet in the front attracts while the magnet in the back repels, which pushes the magnets in the middle to move forward in unexplainable speeds. To keep it moving, the magnets in the guideway push and pull the train. Since the magnets in the guideway are charged up by controlled currents that constantly alternate, they can easily change their push and pull poles quickly to push the train forward, and thus how a Maglev train is created and used.
Reflection- The most thing I've learned from this research topic is how the magnets repel and attract in order for the train to start moving, which is what I've discovered, a much more eco-friendlier way for vehicles move. I do not have any further investigations as a result of my research, but I would like to learn more ways of how magnets are used in our everyday lives. The most difficult part to accomplish was how to be elaborate
Ever wondered how roller coasters work? It’s not with an engine! Roller coasters rely on a motorized chain and a series of phenomena to keep them going. Phenomena are situations or facts that have been observed and proven to exist. A few types of phenomena that help rollercoasters are gravity, kinetic and potential energy, and inertia. Gravity pulls roller coasters along the track as they’re going downhill. Potential and kinetic energy help rollercoasters to ascend hills and gain enough momentum to descend them and finish the track. Inertia keeps passengers pressed towards the outside of a loop-the-loop and in their seat. Gravity, potential and kinetic energy, and inertia are three types of phenomena that can be observed by watching roller
Because of the job opportunities in the West that were advertised throughout the World , many people who found themselves out of place after being freed, or having their livelihood freed, sought to take up shop and make their way to these new opportunities.
Magnets are everywhere! They are in telephones, computers, stereos, vacuum cleaners, refrigerators, washing machines, cars, compasses, TVs, VCRs, your doorbell and many other places. The earth itself is also a magnet. The Greeks discovered a mineral over 2,000 years ago that attracted things that were made of iron. This mineral was found in a part of Turkey that was called Magnesia, so they called it magnetite. A magnet is any material that attracts iron or things made of iron. All magnets have two poles, exert force on each other, and are surrounded by a magnetic field.
“Even though roller coasters propel you through the air, shoot you through tunnels, and zip you down and around many hills and loops, they are quite safe and can prove to be a great way to get scared, feel that sinking feeling in your stomach, and still come out of it wanting to do it all over again (1).” Thanks to the manipulation of gravitational and centripetal forces humans have created one of the most exhilarating attractions. Even though new roller coasters are created continuously in the hope to create breathtaking and terrifying thrills, the fundamental principles of physics remain the same. A roller coaster consists of connected cars that move on tracks due to gravity and momentum. Believe it or not, an engine is not required for most of the ride. The only power source needed is used to get to the top first hill in order to obtain a powerful launch. Physics plays a huge part in the function of roller coasters. Gravity, potential and kinetic energy, centripetal forces, conservation of energy, friction, and acceleration are some of the concepts included.
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.
...late 17th century, and beginning of the 18th century, transportation was favored by American society so much, the wealthier would hire chauffer’s to take people places. So not only did the motor produce a better and more efficient life style, it also created a huge business industry, as we know it today called, “valeting”. The actual motor worked like this. “Two cups filled with mercury would contain a magnet and a wire with one being fixed and the other free to move. Whenever a current was passed through the wire, the free moving magnet or wire would revolve around its fixed partner due to the electromagnet forces being produced.” (History of Innovation). This first motor was a prime example of the fact that movement could be created by electricity and electricity could be created by friction. This motor was the most useful and applicable invention in the 1800’s.
There are three types of magnets. Permanent, temporary, and electromagnets. Permanent magnets are the most common ones. Once they are magnetized they stay so (although they can lose much of their magnetic force). They can be metals found in nature. Temporary magnets hold the properties of a magnet while in a magnetic field, but lost these properties once the field goes away. An example of this would be a paper clip that is charged and can act like a magnet for a short while. Electromagnets are wires wrapped around a metal center(usually iron).
You apprehensively walk up the iron steps and onto the platform. You’re reluctant to go any further, but your friend eggs you on, saying, “It’s not that fast.” You step into the seat and pull the harness down over you. No, this isn’t the latest, greatest technological frontier. It’s a roller coaster. Since 1804 when the first wheeled roller coaster- called “Les Montagnes Russes”- was constructed in Paris, France, roller coasters have been a staple of adventure and fantasy among children and children-at-heart. But there’s no magic involved with these fantastic creations, there’s a plethora of forces and laws governing their every movement. From kinetic energy to inertia, roller coasters are intricate engineering marvels that function through the laws of physics. This is a look into those physics that result in a thrill ride unlike any other.
They exert a force on the train of cars to lift the train to the top of a vary hill. Once lifted, gravity takes over. The remainder of the ride is an experience in energy conversion. The car is pulled to the top of the first hill at the beginning of the ride, but after that the coaster must complete the ride on its own. You aren't being propelled around the track by a motor or pulled by a hitch. The conversion of potential energy to kinetic energy is what drives the roller coaster, and all of the kinetic energy you need for the ride is present once the coaster descends the first
California's plans for a high-speed rail system are coming undone as indecision over routes undermines progress, the Los Angeles Times reports.
The force of a magnet is caused by the magnetic field around the magnet. A magnets gets its magnetic field from moving electric charges. Everything is made up of atoms in the world and atoms have electrons that orbit around them. They create a small magnetic field. The electrons move in different directions so they cancel themselves out, but if you get them going in the same direction
This alien themed roller coaster is a one of a kind riding experience. This ride uses a form of electromagnetic propulsion to propel the car forward. Electromagnetic propulsion is the same technology used in maglev trains. The technology used is a non-contact force, meaning it pushes or pulls on an object without actually touching it. This technology is also an example of newton's third law.
Electric currents produce magnetic fields, they can be as small as macroscopic currents in wires, or microscopic currents in atomic orbits caused by electrons. The magnetic field B is described in terms of force on a moving charge in the Lorentz force law. The relationship of magnetic field and charges leads to many practical applications. Magnetic field sources are dipolar in nature, with a north and south magnetic pole. The magnetic field SI unit is the Tesla, it can be seen in the magnetic part of the Lorentz force law F magnetic = qvB composed of (Newton x second)/(Coulomb x meter). The smaller magnetic field unit is the
The various types of magnets are used in countless facets in everyday life. Thousands of industries, including automotive, electronics, aerospace, craft, manufacturing, printing, therapeutic and mining utilise magnets so that their machineries, tools and equipment can properly function.
