  I was thinking about this and I wanted to link to Attwood's PHD Thesis which I found quite helpful when I was watching Professor Laithwaite's Magnetic River Videos. Attwood goes through and gives some diagrams and is quite approachable. spiral.imperial.ac.uk/bitstream/10044/1/35100/2/Attwood-AD-1980-PhD-Thesis.pdf

  Hey Daniel, I'm currently trying to recreate this for a science in-depth study. What was the power source you used and how many turns did you do for each stator? Would really like to chat more about how you made this possible. Thanks

  Hi Daniel! Great video! I know this may be a long shot since this video is 2 years old but My student design team at my university has been trying to develop our own LIM for the last couple of years. We’ve gotten very close but are having trouble in a few aspects. Specifically generating enough power to actually make a flywheel move, when we try to implement our concepts on a Larger scale. We would love to contact you and discuss our designs with you if possible. If you have an email address where we can discuss in details. That would be great!

  The most important thing in this video is the missing information. You should have given the credit to Prof. Eric Laithwaite who gave the idea of levitation using linear motor technology. I don't see in your video a reference to Prof. Eric Laithwaite. You are stealing material and concept from others and pretend as it is yours. I would strongly suggest you to do a search on Prof. Eric Laithwaite and find out how he he educated the whole world with crystal clear explanation practical implementation etc. I did not like your video and neither I gave you a thumbs up or down. But appreiate your work that is a copy of Prof. Eric Laithwaite.

  How did you fabricate the laminations? Motors like this have one HUGE problem. They need iron behind the mover to complete the magnetic circuit. Without that, the magnetizing current is 2 to 3 orders of magnitude higher than the working current. If you put the iron behind the mover, you must deal with an attraction force that is about 10x the working force. Or you can have 2 stators with mover between to at least largely balance out the attraction forces. The mover's structure needs to mirror the stator's structure, with slotted iron with aluminum or copper closed loops in the slots, to achieve any sort of reasonable efficiency. If you intend to run the motor "open-faced", the flux density is so low that you should change the geometry of the lamination slots. They should widen out in the bottom almost to the point of breaking through to one another, to permit more room for heavier windings to carry the large magnetizing current. Design like yours (except double-sided with aluminum fin between) is used on numerous "launch" type roller coasters. The efficiency is so low that insane utility power or energy storage is required along with insane cooling to get it to survive. For this reason, that design has been abandoned in favor of permanent magnet synchronous motors.

  Would you like to try making a linear induction motor with sea water. Sea water is certainly far less conductive than copper or aluminum, but it is still conductive. Magneto hydrodynamic works just barely but relues on an anode and cathode that also consume a big chunk of energy splitting water. Maybe hydro magnetic induction has potential to be more efficent. Ring launcher magnetic wave down a long iron rod, or A long linear induction tube with three phase ac.

  I'll never forget the 1st time watching the "Magnetic River" and "The Circle of Magnetism" Eric Laithwaite is the inventor of the Linear Induction Motor (LIM) he's also the father of Maglev. This guy was levitating shite back in the 50's and you'd be hard pressed to find anything on him. The Royal Institute black listed him for doing research with gyroscopes disproving laws of physics. He was the only presenter of the Christmas special at the Royal College to do 3 specials, this is the platform of Michael Faraday and other's that invented electricity in the beginning. You can find some of his patents online along with his assistant and co-inventor last name Easton.

  I am just amazed that this works as well as it does. I saw coils made for maglev trains. The coils were busbar copper material. The thickness was just fat metal material connected together. They also use aluminum bus bar as the cost is cheaper and you can go roughly twice as far per pound. That is what the working med said. Job well done Daniels Electronics Lab.

  Daniel, I enjoyed this video. It reminded me of talking with my father about electrical device designs (I wish I had paid more attention but I chose to go into aerospace composites and machining). My son is considering following in my father's footsteps and becoming a EE. He is starting college in the next couple of years so I will be playing your videos with him to help inspire him and help with the difficult decision of which engineering discipline he wants to go into. Could you please explain a linear generator? I'm trying to understand creating electricity inside of a tube utilizing a toroidal Halbach array moving up and down inside of copper coils wrapped around and outside of the magnets. The coils would be stationary. I am most curious about all materials used, the number of coils turned, is a Halbach array a good idea, us it useful to multiple coils and magnet segments, what goes into determining the distance between the magnets and coils and any other ideas you may have which I should pay attention to. My agenda is to charge a 12V battery. Thank you in advance! All the best, Steve

  A "simple" question before I even finish viewing the video: Can we do a practical mag-lev <thing> without using 3-phase? Seems everything I've viewed so far uses 3-phase for the propulsion aspect. Me, I'm OK with 2 phases that are 180º out of phase, creating double the voltage across the actives... but once we have 3 phases 120º out of phase... just obtaining it is insanely complex (assuming you don't have a 3P supply to your house), and understanding the math across the phases is worse. And that's before trying to work out current-lag, collapsing-field reverse current, hysteresis and all that crap. That's where I left my studies in electrical theory, many years ago. Listening to your "power supply", it sounds like an old-school mechanical rotary inverter, artificially inducing local 3-phase from a single-phase supply. They used small 'dynamotors' back in the 2WW, to produce 1 and 3 phase power from a 24V accumulator, so the concept isn't exactly cutting edge. I still HAVE one, that works, tho the efficiency is terrible. You see why I detest projects that require 3 phase energy of any voltage. Please tell me that there is another way to do these experiments that doesn't require 3 phase power?

  Interesting question. Have you watched the magnetic river videos from professor laithwaite? Using one magnetic field you get a point that will not be stable. Using a second field you can get stability. In his magnetic river video he talks about thinking they would need to provide a fan or separate motor to get propulsion. They overcame this by breaking the motor up into sections and sending 3 phase through the coils. As they switch on an off you get the effect of having the field flow along down the motor. The machine I used was called a VFD or variable frequency drive. This model does simply take 1 phase power and break it down to DC. It then digitally builds 3 phases that are perfectly 120 degrees apart. With a VFD you can also control the frequency of the waves. You can get that effect by hooking a dc motor to a generator. The generator will make perfect 3 phases based on the three coils in the generator. You also mentioned many electrical things that can be ignored in this simple example. Hysteresis is a material property of the metal in the core but I just used plain steel. Balancing the phases shouldn’t be an issue since they are all the same number of turns. Obviously I’m simplifying but for this level of example it is not needed.

  Yes, mine is only a single row. His in the video has 2 rows. When they are place next to each other they create a magnetic channel that the aluminum wants to stay inside. He likened it to a river bank where the aluminum can’t go too far up either bank before falling back into the channel.
