Exactly everyone makes the claim that it uses superconductors but no one describes how? Is it levitation through the meisner effect or what is it ? How is it used in Maglev trains I dont want problems and advantagesOf course maglev trains use superconductors!
Main problem is cost, as laying out many miles of solenoid tracks as well as creating an entirely new infrastructure would cost a lot of money.
Currently, a maglev system is currently being used in Shanghai, but other countries such as Japan are still trying to create a commercially viable system
Maglev trains do NOT use the Meissner effect - the trains are simply 'dragged' along and levitated by repulsion/attraction between magnets on the bottom of the train and magnets on the rails. The only reason that superconductors are sometimes used is because they can act as very strong electromagnets with no power loss. If they are used, they are (usually) used only on the train rather than the rails (or both), because the cost/effort of cooling them is less when they're on the train.Exactly everyone makes the claim that it uses superconductors but no one describes how?

Why would you HAVE to use superconductors?I was under the impression, the Maglev Train (Shanghai was an example I read) uses superconductor technology in providing levitation, as the magnets on the train are unable to penetrate the superconductor material on the track thus form eddy currents instead, which under Lenz's law, works to oppose the original source of change and hence repels and levitates the train off the track a few centimetres in the air.
Piss poor explanation, but I think the HSC understanding of it would be to assume Maglev Trains utilise superconductor technology even if in 'reality' (most of the HSC Physics course isn't really relatable in reality) it's a different story.
I'm sure you wouldn't HAVE too. Tbh I'm not aware of the other alternatives you're implying, but that's the crux of the reasoning behind the use of superconductors in the maglev trains, which the HSC Physics syllabus requires you to regurgitate.Why would you HAVE to use superconductors?
It is not necessary to use super conducting materials. You can do it with permanent magnets as well.Maglev trains certaintly utilise super conductors.
