Help me survive: / ludicscience The magnetic levitator is a fun and amazing toy that you can build with little effort. Here we show you how to make your own.
I'm a few years late to the magnet party but this is the coolest thing I've seen on RU-vid in a while, even better than the cucumbers scaring the hell outta housecats video!
That's cool but I wonder if you could get another magnet or 2 on a screw-type assembly in the place if that bar connected to the pin. With the screw assembly you could make fine adjustments to the position of the magnets so they can (hopefully) do the job that the pin is doing, mainly, keeping the axial direction stable.
Hello my son is trying to do this experiment but isn’t successful Can you please share how to make the tube. Can he stick the neo magnets to the end of a plastic rod. What should be the length of the tube or plastic rod .
Hi the length of the tube in not important. I used a transparency sheet and rolled it to the diameter of the magnets, then glued them. He can use any rod or tube and glue the magnets to the end
If the stabilizer piece of wood (the one against which the thumb tack pushes) is placed slightly further from the center of the platform, and an additional small neodymium magnet is adhered to it (with hot glue, for example), turned so that it's polarity is opposite to that of the magnet to which the tack is currently adhered, would the new magnet not repel the tube while still holding it in place? This way the tube would have no points of contact with the platform at all.
Very interesting. If you were to add 2 more sets of speaker magnets perpendicular to this arrangement, so that the speaker magnets form a square, and add to the clear plastic tube so that it made a + sign, and two more neo magnets in the two additional ends of the tube - then would this be levitating in a stable manner? I think handling the push and pull of the magnet interaction on 2 axis of movement at 90 degrees to each other could make it so you don't need to have the piece of wood and the tack on there. It could be free floating.
I have an idea for a lifting force machine. Step 1: Get hollowed out cube. Step 2: Securely attach magnet to inner bottom of hollowed out cube. Step 3: Place a lever on inside bottom of cube behind the magnet that's securely attached to inside bottom of cube so that one side of the lever is pointing towards you and hanging over the magnet. Step 4: Attach a vertical bar to the top side of the part of the lever that is not hanging over magnet witch is securely attached to inner bottom of cube. Make sure the bar goes all the way up to the inner top of the cube barley touching it. Step 5: Securely attach a magnet to the side of the lever that is hanging over the magnet that is attached to the inner bottom of cube. Note: Magnets need to be facing each other with attracting poles N,S or S,N Note: The lever is going to have to be really close to the magnet on inner bottom of cube because of how close those magnetic fields need to be to interact. But not so close that magnets can touch. The magnet on top connected to lever is pulling the magnet on inner bottom of cube towards it and since the magnet on inner bottom of cube is connected to cube, this pulling force acts as a lifting force. Now at the same time the magnet on inner bottom of cube is pulling the magnet on top downwards BUT the magnet on top is connected to the lever so any downwards pulling force is being converted mechanically by the lever into upwards lifting force. Now if you know anything about magnets you now that there are magnets powerfull enough to lift far more weight then just there own. So essentialy this divice is exploiting the powerfull pulling force of magnets by mechanicaly transforming its magnetic pulling force into mechanical lifting force through the clever utilization of a lever, and walla stuff can be made to fly. Imagine if the magnets in this experiment where electro magnets so the ammount of electrical current going into them determined the ammount of lifting force that it would have. Now imagine this system being used as an attachment that could be placed under or ontop of vehicles to counter the weight of the vehicle and any cargo its carying. Now imagine if this was done with powerfull permanent magnets and turned sideways and placed in an electric generator and had enough strength to pass through the magnetic fields as it propelled itself forwards with its own magnetic pulling force.

I have connected 20 Maxwell 2.7V super capacitors in series and I am going to spark, but with each spark the voltage decreases a little from the capacities. The total charger of these 20 capacitors is 55V DC. How should I connect them together that 300 output voltage?
Instead of using the wood and thumbtack, would it be possible to use 2 magnets at a certain distance apart of opposite polarity to balance the magets in the tube? Also, if you were to apply voltage to the neodymium magnet, would that create a magnetic field and cause the tube to spin? Sorry for the questions. I am new to this kind of material and am interested in learning more. Your videos are very helpful!
+Ludic Science Would you be able to recommend any books on electricity and magnetism? Ive been watching lectures of Walter Lewin regarding the topic, but the more sources the better.
what will happen if you electrify one side left or right side of the speaker magnet? will it propell the hovering towards the side that is not energized?
Hi, nice video, thank you for sharing. If the transparent floating stick is smaller than the gap between magnets on board, you should not need the front plate to stop the stick ? Or it doesn't work ?
Let me give an explanation that makes sense. You always need the front plate is not an explantion. I will make a video and I will explain everything. And if I miss to say something I will cover it in the description.
Hello, I'm studying in an engineering school and I've got a project to develop in the same way than yours, so, I've got some questions to ask : 1) What's the price for those magnets ? 2) What specific kind of magnets did you use ?
Hello, I'm studying electronic and communication engineering. Magnetic Levitator is my project of finish my school. But I dont know that materials and I dont know names of materials. Can you help me about my questions, please? Have a good day
What so every pole becomes repulsive? That's odd I'd assume if it spun it would've attracted to the bigger magnets no one the poles became repulsive unless north is the flat side and south is the whole ring
Ludic Science yea , your right , the closest I gave found of someone levitating an object in free space is only achieved by A: two or more sound waves hitting each other or B : using another magnet as the levitator.
ok everyone i have a question i have my wood set up with my big magnets and I have my tube with the two smaller magnets but my tube is not levitating on one side it is being attracted to my bigger magnets but the opposite side will levitate. i have tried rotating and tried other magnets out of the package I bought. can anyone help me my son is trying to get this figured out for his science experiment. thank you
When you place two circular or any magnet flat on a table. If their opposite poles are facing up, their side will attract. If the same poles are facing up the side will repel. Now that is much more clear. Now based on that as an actual fact, isn't there an obvious question to ask here? The only way to know that, you actually have to pay attention. There is no way to ask an obvious question if you don't even pay attention to actually see what is going on.
+darkgirl3422 Also an unstable configuration. In order to do that, you need to add control electronics for a dynamic control of the magnetic force. Something like this: uzzors2k.4hv.org/index.php?page=magneticlevitation
Get yourself some doweling (round wooden stick, you can get at a hardware store) that is the same diameter as the smaller magnets. Wrap the material around the doweling, glue it in place and, remove the dowel.
Philip Jones yeah I fcked it up brought it in class and it fell apart lmao. But at that point the teacher was so done with her job she just gave everyone an A
Castiel Hamidi This one should do the trick www.supermagnete.de/eng/block-magnets-neodymium/block-magnet-50.8mm-x-50.8mm-x-25.4mm-neodymium-n40-nickel-plated_Q-51-51-25-N
Ludic Science are you listen Mr could you make a stand alone top which can prevent sugar from ant's since I have nothing to loose but my rational mind doesn't allowed me to loose so what I gained or losing
Hi there. This question is for anyone who has the knowledge to answer it. I am trying a cool effect by trying to levitate my computer monitor screen(about 9lbs) above my desk. I have found that neo magnets may be the bast option. However, I have no idea what size or "N" level or something that I would need. I also am wondering what shape I would need. I have found that disk magnets may work but I have no idea like I said. Thanks! -Harrison
With the old CRT monitors, you might get away with levitation but your screen would not work. As for having very strong magnets next to complex electronics, not such a good idea.
They are not speaker magnets, this guy's a moron. They are from a Magnetron in a microwave oven, just find some junk microwave's and take 'em apart...simple.
