No magnets used in this experiment, unless you count the one in the speaker. This is basically a refilmatization of an old video where I put salt on a 3,5" speaker and ran frequencies throught it with an online tone generator. I found the patterns that emerged absolutely fascinating, but at that time I didn't have any slow motion option. Now I filmed the experiment again with slow motion captures at 960 fps or 32 times slowed for a closer look. As a bonus I also tried glitter. My old speaker has seen better days as I have tortured it with multiple cymatic experiments. I found a same size computer speaker set from a flee market with 5 euros. This is an easy and an inexpensive experiment with great results. I highly recommend testing this - great experiment to show your kids or just marvel at it yourself. ... https://www.youtube.com/watch?v=k9bW9Ua13Cs

Diamagnetic suspension levitation of checkerboard pattern magnetic array. A magnetic array with multiple south and north poles facing a diamagnetic material, such as a pyrolytic carbon block, provides surprisingly lot of lift. Magnetic Flux is densest where the south and north pole are making contact, that is where the most lift comes from. Heaviest single magnet that I have been able to succesfully levitate over pyrolytic graphite is about 20g. In a checkerboard pattern array there's a lot of conflicting polarity with respect of the top attracting magnet, this is solved by attaching a strong attracting axle magnet to the array. 5 mm N50 cube magnets sponsored by supermagnete: http://sumag.net/w-05-n50-g-i01 5mm N42 cube magnets sponsored by supermagnete, grade N42: https://sumag.net/w-05-n-x01 30 mm sphere magnet provided by supermagnete: https://sumag.net/k-30-c-x01 Music: Jesse Gallagher - The Inner Sound ... https://www.youtube.com/watch?v=Q4vMXSqoTyg

Instead of wind, these chimes are powered by magnetism - generating a repeating hypnotic melody with a gradually slowing down tempo. Amazingly mesmerizing! Instruction on how to built the chimes: I used ∅10 mm copper tubing. Copper is a soft metal which makes it easy to work with. Harder metals will produce cleaner sound, but I personally like the softer tone of copper. I tuned 8 tubes into C major tuning - one octave of white keys in the piano. Shorter chimes produce higher-pitched tones. In the ∅10mm tubing, I used the shortest chime (High C) is 100 mm and the longest chime (low C) is 142 mm. It is best to drill the holes beforehand because it will make the pitch a little bit higher. It is easy to polish the copper pipe by rubbing it with steel wool, or with scotch pad. I installed an app called Pano Tuner to my phone. It did the job well, I was really satisfied on the accurateness of the tuning. The chime needs to be hanged from a string when the pitch is tested, otherwise it won't be able to resonate freely. A thin string works best. A thick string will reduce the sustain. I used black sewing thread. Once one length of a specific tone is determined, determining the rest will become easier. In major C scale intervals between C-D and D-E are whole steps but the interval between E-F is a half step. Intervals between F-G, G-A, A-B are whole steps, but interval between B-C is again a half step. This means the length difference between E and F & B and C are shorter than with the whole step ones. Tone needs to be approached from below - once it goes over it cannot be lowered, so a lot of testing between the sanding is required. I was surprised on how effectively sand paper grinds copper pipe, no power tools are required in this step. The sand paper I used was 80. It took me little over an hour to get the 8 chimes tuned. If you are planning to make a wind chime with five chimes, pentatonic scale is a commonly used in wind chimes, using tones A, C, D, E and G is a safe choice. My previous project was a magnetically supported flywheel that spun for over 10 hour on it's own momentum. I noticed the flywheel had become magnetized while spinning under a strong magnet. I had an idea to use the magnetized flywheel to "power" the chimes, instead of wind or a drum stick. I cut 8 little strips of metal, magnetized them by sweeping them 50+ times to the same direction with a neodymium magnet. Then I measured the middle point and and used a hammer and sharp metal marker to make a little dent to the middle of the strip. After that I placed the metal strips on a tip of a non-ferromagnetic stainless steel screws. This results the metal strip into behaving like a compass needle. I built little hangers out of wood for each chime. Then placed the hangers, chimes, ... https://www.youtube.com/watch?v=7oYVBhIkvJ8
