In this magnetic experiment I show you how using a Halbach array can double the power of the magnets. This particular arrangement of the magnets, bound by means of glue allows to almost double the magnetic field from an array side while the other side the magnetic field is almost zero. The array of Halbach find practical applications in the Maglev train and in particle accelerators. | Magneticgames

Magnetic Chaotic Pendulum: this beautifully designed “perpetual pendulum” has been in my collection since 1990. The ufo shaped bob has a magnet embedded in it and the base has a battery and simple coil circuit that gives the bob a tiny push each time it swings through the center. An array of 5 permanent magnets are also hidden in the wood base (wait for reveal with magnetic viewing film) and these magnets produce the chaotic motion- not random, but very sensitive to slight differences in initial
