Hi Andrew, Do you realise that you could have saved 50% of magnets, without losing any strength? Now each layers has six magnets in a start orientation. Instead, you could have used three magnets per layer, going around in a loop, 1-2, 3-4 and 5-6. That would also saved you the central steel pin, which could be a simple screw. Inspired by your video, I bought the steel and magnets, and confirmed this finding. Of course a new challenge is how to get the magnets in there. My trick is to have a pause in the gcode, put the magnets in, and then continue the print. Thanks again for the inspiration! Oskar

@OskarPuzzle3 жыл бұрын
@@AndrewKleinWW Thanks! Yes, I am designing and making all puzzles on my KZbin channel myself, including the colorful Magnet Unlock puzzle. I have been using my own 3D-printer for the last year. Where is your extra factor 9 coming from? The order of the three disks is immaterial to the solution, and so is the placement of the first disk. Once the first disk is in place, then there are 12 options for the second disk (6 rotations + 6 upside-down), and 12 for the third disk. So 12x12=144.
@AndrewKleinWW3 жыл бұрын
Sorry, should have said I got 1728 configurations. That was with ordering included, since there are 6 ordering setups you divide 1728 by 6 to get 288 if ordering doesn’t matter (do you really eliminate all external field with the solution in any of the 6 orders?). So I’m still getting 288, not 144, because I was counting the flip of the first disk as well as flips and 60 degree rotations of the second two.

Thanks Andrew, for the nice design for a mag switch and the clear explanation of the working principle. I am planning to make my first mag switch with plywood. I feel, there are advantages if you use cube magnets and steel rods with square cross section. - A 10x10x10mm cube magnet has 127% of the volume of a 10mm dia x 10mm high cylindrical magnet. - 8 cube magnets can be used instead of 12 cylindrical ones and the rotation angle will be 90 degrees. - Since there are no curved surfaces anywhere, the cube magnets will have a larger area in perfect contact with the square rod at the center as well as the peripheral rods, resulting in a stronger mag switch even though the number of magnets is reduced from 12 to 8. - Cube magnets and square rods are easily available. - If the device is going to be 3D printed, it's only a design change. However, if plywood is to be used, making a square hole may not be that easy. Looking forward to your comments. Thanks.
@Bright88885 жыл бұрын
After posting, I created the model in Sketchup and realized that the central rod has to be necessarily circular in order to rotate the top portion by 90 degrees. However, this issue can be resolved by making the central rod circular. This will of course introduce curved surfaces and may make the switch less powerful. Building the models and testing them will provide definitive answers.

awesome follow up and lesson on how it actually works. now I have to get someone to print it for me. it's interesting that the smaller switchable magnet bases machinists use for attaching dial gages etc use one magnet and a few strips of aluminum in a steel case also works, but with only one magnet. I guess the aluminum blocks the flux when aligned with the pole (since the pole is like the "opening" to the flux). are you considering an updated design based on what OskarPuzzle said? I would buy that plan too! thanks!
