how does magnetic levitation work:
Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations. Hello, everyone! I’ve been having problems with my magnetic levitation circuit. Aside from changing out a SS495 Hall Effect Sensor for an A1302, it’s a Maglev (derived from magnetic levitation) is a system of train transportation that uses two sets of magnets, one set to repel and push the train up off the track as in levitation (hence Maglev, Magnetic-levitation), then another set to move the ‘floating train’ ahead at great speed taking advantage of the lack of friction. A while back I published an Instructable for a wireless screen, as part of my GR.9 science fair. Right at the top I mentioned that when the project was done, that I would publish an Instructable on my project, which happened to be Levitation. Now before I get started, I would like to say that the Why can’t we just levitate metal objects with a magnet at the right distance? Because, as a ferrous material nears a magnetic field, the force increases exponentially. The technology of magnetic levitation, or “Maglev,” has useful application in the development of high-speed trains. .
What is a homopolar motor used for? In truth, they aren’t that practical at all. Unfortunately, you will never generate enough power from a homopolar motor to power any domestic appliances but they are great fun to make and really useful for demonstrating the effects of electromagnetism and how electric motors work. (Molecular Magnetism and Levitation) Seeing is believing: A little frog (alive !) and a water ball levitate inside a Ø32mm vertical bore of a Bitter solenoid in a magnetic field of about 16 Tesla at the Nijmegen High Field Magnet Laboratory. FUN WITH DIAMAGNETIC LEVITATION. Earnshaw’s theorem from 1842 states that the stable levitation of a permanent magnet is impossible without an added force for stabilization. A person pulls the wire with constant velocity through the magnetic field. As they do so, they have to apply a force. The constant magnetic field can’t do work by itself (otherwise its strength would have to change), but it can change the direction of a force. .
