This project definitely goes to my to do list, amazing project with such less components ❤

Ceramic repulsion mixed with just the right amount of electromagnetic attraction.. Nice

VERY GOOD DEMONSTRATION, I LOVE IT!!!

This is really amazing! I know the commercial devices that perform this function (complex devices with lots of electronics) and seen also very old schematics that made something similar but also, with much more electronics! It is very surprising that the magnet can be maintained over the electromagnet (repusion) in such a simple way! I'm really surprised! Thanks for sharing this information.

It was the best training video I saw. You really helped me a lot. Thank you❤

Beautifully done, thanks for sharing

Great video !! Thanks for sharing. Greetings from Argentina

Thank you for the training you really gave me. I hope you are successful❤🙌

That is so stable.. Lovely.... Btw Where are you from ?

can we use other linear hall effect sensor like A3144

Hello, what's the length of the wire? How do I calculate the number of turns. Or I'll do the same as you did, how is the coil made

Very good project can I use 4 coils to use big levitating magnet

Very Good Idea,

Thanks for amazing video.

Best one i ever seen

Can i use ferrite magnet in this project as a levitate object?

excelente amigo

Wow amazing!! Imagine you were able to make the electric energy travel from the electromagnet you creted to the magnet that is connected to a lamp, will that turn on the lamp??

is good to add an iron screw in center of the coil?

It's amazing. Is there a conection diagram? I'm neaby in this so somethings are not so clear for me. I want to replicate. Thanks a lot.

what if we want to levitate more higher? how can we do it ?

Let me see if I can figure out the principle of operation. It appears to me that as the magnet gets close to the hall sensor, it causes the hall sensor to have and output which turns on the transistor. Both the coild and the ring magnet below has its opposite pole to the suspended magnet so therefore it should get sucked down, attracted and not float.

​@Hobby Projects Hi Hobby Projects, Recently I discovered your informative site. I am a hobbyist and I find almost all your projects novel and interesting. After watching your video, I have successfully completed the magnetic levitation project in which a neodymium magnet is suspended under the coil. This I managed to do without using an arduino or any other microcontroller. Now I am trying the project in which a magnet floats over the coil. My problem is, the neodymium magnet does not remain stable over the coil; it always flies away and gets stuck to the ring magnet. The size of the ring magnet I am using is 90x36x15mm while what you have used is 100x57x20mm. Is the smaller inner diameter (36mm instead of 57mm) the main reason for my problem? Looking forward to your suggestions that will help me to complete the project. Thanks.

I think neodymium magnets are too powerful for this type of simple system, this type of simple System cannot control it, use smaller neodymium magnets or feraid magnets.

Hello sir . My name is Ali. I did not find hall sensor 482 and TIP 122.But I have hall sensor LM36 and TIP 42C .The device did not work so what solution.Please

teşekkür ederim çok güzeldi

what was the coil resistance? the video skips at the part where you measure it.

Hello. Please tell me the analogue of these hall sensors. We don't have those in our city

Its quit easy to make. But please tell the turns of copper coil for electro magnet

Looks magical :D But for what is the nail for?

@hobbyprojects

Thanks. The nail was used for balancing purpose. Without this the levitating magnet wasn't stable, tends to rotate around, flipping itself and attracts to the ring magnet.

Very, very nice project! 1) Why must the electromagnet be an 'air core' ? Why not solid core?

@hobbyprojects

5 жыл бұрын

Thanks. I had tried it by using Iron core but found the better result with air core electromagnet. The levitation distance was effected by the iron core. Sometime the levitating magnet sticks to the iron core randomly.

@@hobbyprojects Exactly. The ferrous magnet creates one field while the electromagnet creates an opposite field. The two combined creates a conflict. Repelling, keeping it away. But attracting, making it not leave. If the center of the electro magnet had an iron core, it would change the field and either push it to one side and down or pull it in and down.

How much weight it will take on it plz reply

Outer Diameter of magnet 100 mm, inner Diameter 57mm, height 20mm Coil size height 20mm, width 18mm approx. Wire thickness .2 mm aprox. You can also try with .3 mm.

The linear hall sensor allows to adjust by continuous loop but only vertically, what about the instability of other axis? It is hard for me believe, because atleast 3 or 4 coils would be needed to achieve stability in the repulsive levitation... Explain me.... I don't understand the physics here, it's weird...

im a little confused too. i hate to suggest this video is fake and that the circuit you claim your using isnt true but i have a hard time believing this. the transistor switches power on/off to the electromagnet and this is controlled by the hall sensor, right? while the electromagnet (el.mag for short) is on it should repel the floating magnet assuming the el.mag is an aircored solenoid. If the el.mag has a core (like iron or steel whatever) then the dl.mag should attract and pull the floating magnet. If we forget about the electromagnet for a second, lets talk about the relationship betweeen the ring magnet and the floating magnet. In the position shown in your diagram the small magnet will experience both a force of repulsion and attraction due to the unique field shaping of the flux lines of the ring magnet and how it differs from the shape of the field that encompassed the smaller magnet. the ring magnet and small cylinder magnet, due to the difference in the shape of their fields, if you arrange the poles like it shows in the schem, the lines of flux within these fields arrange themselves in a way that creates a sort of 'pocket' or 'node' in the space above the ring magnet that the small magnet can almost 'rest' on but its not stable enough to lock the small magnet in place. the smaller magnet will experience and force of pull in all directions horizontal to the plane of face of the ring magnet. it will also experience a force of repulsion along the vertical y axis in a direction perpendicular to the direction of the forcd of pull. With just this setup the magnet will not sit still in this spot and is pulled to the side and towards the ring magnets surface.

what size of wire did you use? plz answer

I think the idea is to create a magnetic feild with it. So just about any gage wire should work, but may require more or less windings which you can do by trial and error starting with more than less.

Magnet dimensions??

That Arduino cable could be longer. I could just put the device on the laptop

i buid both , it works so beautiful , sometimes there is a different character diagramm of hallsensors or mosfets , the simpliest and garnatie that s it is works , it s need a trigger poti between gate and source by the mosfet( 1k) or resistor at last ,, with this you set the trigger with it , so all hall and mos are work , the 1 K resistor do not work by every parts , with this you can find also the trigger moment , the second resistor is then for protection for the hall ,,,,,,,,, i say thank you , special for the standing levitation prinzip !

Like in Brazil

how much current your levitation is using ,,, by the coil with 26 ohm and 12 volt. i have just 7 Ohm coil and 300mah current /12volt ,my coil is centert in a Aluminium stick , so that i can ajust the coil niveau very easy (high&down ) , it works very stabil with 8mm levitation distance , i am very happy for this challenge ,and fight for it till it s done , i look myself to make a video for this cute pretty very cool new update 2019 device , fully reduction prinzip , but it must said , it s more heavy to build it , than the hang version , remark : my version circuit is identical with yours , but without the 5 Volt IC stabi , so one part less , it do not need the 5 volt stabi .

Without nail the magnet can levitate

@AngryHybridApe

3 жыл бұрын

Not likely. The magnet would probably flip over and drop. With the nail on the magnet, the nail is magnetized and helps create the opposing field.

Hello plz reply me

It's not working 🤨

hmm interesting 🤔 🧲 flipping the magnet creates new engineering processes??
