physicsfun Feel Flux Loop: original (copper) and the "Skill Flux" version (aluminum)- toys that use Lenz's Law to manipulate a very strong neodymium magnet. The magnet falls a bit faster through the aluminum even though the walls are thicker- Al is only about 60% as conductive as Cu- so it takes more material to induce the needed magnetic field using aluminum. Interestingly the Al tube is about half the mass of the Cu one, even though it is larger in volume. ➡️ Follow the link in my profile for details on where to get this set and many other items featured here on @physicsfun #feelflux #skillflux #lenzslaw #neodymium #magnets #magneticfield #eddycurrents #induction #Faraday #electromagnetism #electromagnet #aluminum #conductivity #copper #physics #physicstoy #science #scienceisawesome
