Experimenting with the Halbach Array. Part 03

this is a hell bug array at least my version of what most of the time the magnetic orientation diagrams of them look more like this black arrow usually indicates more I'll be doing things with my outlook array that most people don't try them all what is a out bug array a hal baccarat is an arrangement of permanent magnets which increases the magnetic field of one side of the array while effectively canceling out the field to nearly zero on the other side of the array the how big array was created by physicists Klaus Howick in the 1980s as a way to focus accelerator park beans what's it used for public arrays are used for brushless AC motors and magnetic coupling you'll find them in efficient voice coils wiggler magnets used in particle accelerators and free electron lasers it's also the key component in the induct track of maglev train system the simplest application though would be that of a refrigerator magnet the fact that your refrigerator magnets are made of Halbrook arrays is why they stick to your refrigerator when you place them with a printed side of the magnet showing this is the side that has audited magnetic field cycles and they fall right off if you turn them around in magnetically cancel side if you use magnetic film it's quite easy to see the al-bukhari effect demonstrated the magnetic field lines are barely visible on one side while highly pronounced on the other quite often I will revisit designs if I think of new fins I want to try or if I see something new I could learn from them I tried using permanent magnets with the hologram to achieve rotation and motive force in my first two videos dealing with the array but I didn't try using steel ball in fact I've never seen anyone try using alabang array to move a steel ball down a track so I thought what a great opportunity to learn something things and expand my knowledge by the end of this video I had a really interesting revelation so you might want to stick around until the very end because it's a pretty interesting idea an idea that I've also never seen anyone try for those of you unfamiliar with my methods the reason I play setting the card moving it back and forth through the entrance and exit ways is to determine if there's any motive force can be generated basically if the magnets around the track are able to draw the card into the magnetic field and expel them out the other end without drawing the cart back in well that's what I'm looking you can take an assembly that does that it's a series of them to cycle continuous motion that's the first thing I'm testing the second is to see if the repulsion of the entry point of the magnets around the track is light enough that the acceleration and the exit point of the cart is great enough to cycle again for continuous motion third I'm checking to see how many cocking points president each configuration that determine the best configuration views for further testing instead of just showing you clips of assemblies that I've already configured into what works best I thought I would show you a little bit of the testing process that goes into determining my final configurations I'm not going to take the time to show every single test but I tested every single configuration backwards and forwards and then I would flip the card and test it in the opposite magnetic orientation backwards and forwards as well that's the correct way to test every build I even tried flipping the house bug arrays so that it's backwards on this version most dramatic results were when I faced it this one now when you expand the array it cancels out the positive effects so you're better off removing the last four magnets and just doing it with the six perhaps putting spaces between them even magnetic shielding between each section you might be able to get some kind of continuous movement going that way okay the reason it's difficulty is out like a rating to achieve motive force is because the poles and the arrays look back and forth between north and south making it difficult for a cart or rotor to align itself properly it's simply cogsa whenever it's in an area of opposing polarity magnetic flux it doesn't have to be the case with a steel ball though a steel ball will follow a North just as easily as a South Pole however problem is that by extending the array pattern the ball is only following the attraction it receives when answering the edge of the array so it slowly winds down because it's just riding wave pattern and there's no variation of that way it's a simple consistent wave of magnetic flux to alter a very the wave would only make it cog in areas where the flux is closest to the state ball the simplest way to explain the effect you get from this experiment is that it's similar to a car coasting up and down a series pills you can build enough momentum from a slight push to get over another hill or two but gradually the car will slow and eventually come to a stop that's of course due to gravity drag the weight of the car etc so the best way around this problem is simply to break up the array into separate units and apply shielding to one or both of the endcap magnets it's possible that you could use the momentum from the initial burst of magnetic force as the steel ball is pulled into the array and then effectively block the magnetic field of the exit allowing the ball to coast into the next series of magnets arranged similarly so generally what I'm talking about is something similar to this I can't say whether you could do a succession of these but you can easily do two or three of these in a row and that leads me into the next idea that I had when I was doing research for this video I ran across a description on Wikipedia which I found interesting they use the analogy that the Halbrook array works similar to horseshoe magnets aligned adjacent to each other which made me think of one our Johnson's magnetic motor designs and so I thought what if I use the Halbrook array in a similar fashion setting up the north poles facing forward with a track setup of successions of ceramic magnets with their north poles all facing up and I noticed it functioned very much like Howard Johnson's linear magnetic north which is an imbalanced system there are three types of permanent magnetic order systems I'll cover what those are and how they work in a future video so stay tuned I'm not sure you can tell here but basically no matter how long you make the track you end up with successions of movement and cogging areas in between meaning that if you took the time to tune the magnets on the track it's possible you can end up with consecutive movement so here's the idea that I had to Halbrook array and Howard Johnson's linear magnetic motor while the magnetic orientations differ the configurations are similar so what if you can find them simply looking at the albergue array using the arrows doesn't demonstrate the magnetic effect it causes and great clarity what's actually happening by forcing the North coils together it amplifies the magnetic field pattern it does this by crowding the electron spins of the center magnet while nearly cancelling out the South Pole magnetic spins Howard Johnson uses a similar technique for crowding the electron spins the magnets and many of his magnetic motor designs so it's obviously going to take some adjustment to compensate for the magnetic orientation variations but this is going to be a fun project to work on thanks for watching take your right to this video give it a thumbs up and subscribe for more tune in next time when I want em to provide a Howard Johnson when your magnetic north design with the help of a to great things
