JREF Forum General Topics Science, Mathematics, Medicine, and Technology PDA View Full Version : Remember my magnets show? athon 12th November 2006, 06:28 PM I asked for some advice on various things you could demonstrate using magnets, for a show on the topic. That was about three months back. Well, I've the past few months touring it. And for those who helped me, I'd like to thank you all for your advice. It was a huge success. There were only a few demonstrations - one involving ping-pong balls for electrons, demonstrating electromagnetism. Another was a copper tube, demonstrating magnetic breaking. I made a 1.5 metre long gauss rifle and used it to shoot down a toy stormtrooper (well, I did have a Star Wars theme to the show...how else do you demonstrate, 'The Force'). I also made an electromagnet. Maybe one day I'll get that rail gun working. That would be something. Athon Soapy Sam 13th November 2006, 03:27 AM Wot's magnetic breaking? (Or do you mean "braking", you quasi literate antipodean person?) ETA- ps Don't suppose you made a video clip?

Contents Methods (Mechanically-stabilized Levitation) Direct Diamagnetic Levitation Levitation Over a Superconductor ... edit Methods There are several methods to obtain magnetic levitation: edit (Mechanically-stabilized Levitation) If one mechanically constrains a permanent magnet with either a string or plate along one axis, one can create a stable configuration in which the repulsion between the magnets creates a substantial levitation. This is not considered true levitation because there is mechanical contact, even though that constraint is usually perpendicular to the vertical levitation axis. A popular toy based on this principle is the [Revolution by Carlisle].
