Maglev Definition and 46 Threads

When using magnetism to accelerate the Maglev, and neglecting the usual frictions, and also relativistic effects, is there any limit how fast it can accelerate to? Or is there any sort of increasing "drag" of any sort native to magnetism, which would get in the way of acceleration, as it goes...

Has NASA considered building a maglev on the moon so we can use the lunar mass and momentum to gain higher energy savings for missions to Mars and beyond? A spacecraft can be catapulted toward the destination with its rocket engines off and only turn them back on to course correct or slow down...

Hi everyone, I'm an Italian High Schooler and I need a problem about maglev trains for the final exam. I apologize in advance if my english is bad or if I didn't follow some rules. I'm not native and new to this forum.

So I am currently trying to model a MAGLEV train using COMSOL (high school research project). My project uses AC and DC motors as alternatives to the current maglev infrastructure and transportation. I first created a prototype through CAD Onshape, then created it in real life and applied my DC...

My little home made air-core solenoid makes 1.5T, why is it that superconducting electromagnets often aren't stronger than one would expect. Take the japanese maglev train for example: http://www.supraconductivite.fr/en/index.php?p=applications-trains-maglev-more According to this article the...

I'm trying to find out why EMS maglev trains use magnetic attraction instead of repulsion. Given that the attractive force diminishes with distance it seems the forces would have to match exactly or else one of the two forces would win out and the train would come to a grinding halt. But with...

Hey all, I have a group project for a Physics II course and the group I ended up with is wanting to do maglev as the focus of our project. I thought the girl that decided to do the maglev project had an idea of what questions she wanted to answer and experiments to perform based on her time in...

What would happen?

I need to find an equation that i can make a word problem out of. This has to be able to be used at the grade 11 level and it is for my Stse project. I tried looking in my textbook for problems to calculate something that has to do with magnetic levitation or electromagnetic but i have had no...

Hi All, I was wondering how I would go about creating a circular maglev track using electromagnets? The idea is to have more control over it and to eventually write a piece of code that would allow changes in the strength of the magnetic field potentially? I was just wondering how it would work...

Hello all, I'm working on a little side project to build something close to a Mag-lev system. I've researched loads around the magnets and have the info' on what conditions I need, current, Field strength, etc. But I'm having issues in finding how that relates to the movement of an external...

Hi there, first poster here. Something has been boggling me and I cannot seem to find the answer anywhere. I really hope that you will help me =) A magnet train in vacuum has no friction whatsoever, right? Then what about electron interactions between the 'rail' and the train itself due to...

Hello everyone, I am thinking of a thought experiment about a so-called "space tower" but don't have enough information to estimate the numbers. I understand the material strength needed for such high structures is huge, because of the weight of the structure. But what if the "tower" would be...

Hey guys, I made a topic similar to this earlier, but after I was informed that my ideas has several flaws that would prevent it from working, I revised it and researched more about my topic. This is my original idea with several concepts that has changed. I am planning on making a mini-model...

How small can a maglev propulsion system be? What's the relationship between the size/strength of the magnets and the load capacity of a maglev vehicle?

Hi all, I am doing a maglev conveyor for my final year project. I need to run a simulation program to do some analysis. The program I chose to do this simulation is Labview. however I am having problems with the mathematical formulation on how to control the airgap and linear motion. I would...

1. Hi, I am currently doing a project which the main objective is to build an miniature Maglev Train Prototype and compare its performance with a Conventional Train. 2. I am having a big problem in the propulsion system of the Meglev Train which is the long stator linear synchronous...

Good night, I'm trying to do a model of the maglev at small scale, but I'm having a lot of problems to levitate and have stability. I have already read Earnshaw theory, but in youtube i see many models working, but when i try do replicate doesn't work. Now i have a rail way with...

Interesting four minute video with a magnetic levitation superconductor train http://www.youtube.com/watch?v=5el1A5B-h3Q&feature=player_embedded Perhaps a good demonstration for teachers

I've done some research on maglev trains, but the equations are too complex for me to solve, etc. I haven't taken calculus nor studied magnetism yet, can anybody explain just the basics of physics concepts used in a maglev train? thank you!

i wanted to do maglev proto model, can u pls suggest me how to do it...

OKay i am a high school student making a model maglev train like the Inductrack design. I haven't started building yet but i know how I am going to make it and since i am using permanent magnets, the cart will not levitate right away. It will have wheels on the sides of the cart on rails to...

Can someone explain the role of eddy currents that produce levitation such as in the floating tube expt or the jumping ring? How is the jumping ring altered to achieve stability? i.e raising the ring a fixed distance above the coil? Like in maglev transportation...or is it just dependant on the...

Hey there! I need to build a working model of a maglev-train, which will hover over permanent magnets on a track, and which will have to have a propulsion system. My question is whether there is a way of getting an accelration not using a propellar? As part of the project, I've been given...

A particular pet idea of mine is that of implementing a nationwide Maglev intercity transportation system. Essentially what I would like to see is a brand-new infrastructure program - - - not totally unlike the interstate highway program of the 1950s. In fact, the maglev guideways would not be...

Hey, I have managed to make model maglev train that uses permanent magnets and metals for levitation. It levitates all right but i need ideas to propel it forward. I have attached a picture showing how the model works. Please reply if you have any ideas. Thanks.
