this is beautiful!! i was doing a project on levitating a steel ball electromagnetically trying to use this similar structure. how can I levitate a steel ball, instead of a magnet....and what type of sensor is suitable for that ? thanks al ot !!
Thank you. I think the best way is to use an optical sensor to measure the position of the steel ball. You can also use a Hall effect sensor for this purpose but the signal to noise ratio will be very small.
Is it possible to levitate bigger objects, I understand in medieval times there was a Hindu idol that levitated off the ground and it is said it used permanent magnets. How is that possible??? I would like to repeat this process how do I go about it please. I am not a scientist. Thanks
Yes, it is. For example, we have levitated objects that weigh about 2 pounds (1 kg) using bigger electromagnets. However, levitation using only permanent magnets is impossible (Earnshaw's theorem). I do not think it was possible to (actually) levitate objects in the medieval times due to the lack of the relevant technology.
Ok I understand, thanks for your reply. Well I am an artist and I wish to levitate an object off from a plinth. Can you advise me on the limitations of weight and shape and how I can build your fantastic apparatus, do I need special know how or not.
The magnetic HINDU idol is disappointing I wish it was true but I get the logic.
Also what if more magnets are placed around the hovering object would it spin if you switch polarity between the poles. I am trying to see what things are possible. How much is the budget for making a machine like you are using please?? If I may ask?? Thanks

It is possible to make the levitating object spin by a suitable excitation. The cost of the magnetic levitation system is $55 for the assembled unit and $43 for the basic kit. Please visit our website in the description for more information.
This magnetic levitation system is specifically optimized to work with the disc and sphere magnets (approximately 3 g and 8 g, respectively) listed on our website. The system intentionally limits the current through the electromagnet to reduce its power consumption and this imposes a limitation on the maximum weight of the levitating magnet. It can, however, levitate approximately 0-10 g additional weight and the shape of the levitating object can be arbitrary.
We also have another magnetic levitation system that can levitate up to 100 g. We can also customize the system according to your specifications and make a repulsive version of the system that allows levitation from a base. The magnetic levitation system in kit form requires basic soldering, electrical and mechanical assembly skills.
I like your style, I've been recently getting into projects with electromagnets. I would like to build a series of my own projects but I need someone with a little background to answer a few small questions that stump me because i've learned everything i know from trial and errors
@SASNIGHTCRAWLER : at cern they have proven that matter increases in mass at velocities close to the speed of light. it happens when you try to speed up a particle closer to the asymptote we reach at C, instead of going faster, the particle gains mass (And bends spacetime a little more) It's time's way of keeping you from going faster than it does. Instead of exceeding your own wave function's propagation, you bump into it, and the energy turns into mass temporarily, either way you'll die.
I think that is possible because the magnetic field lines have the same direction as the force of gravity if not so would fall the iron object or would join it with the electromagnet. If you hold a normal iman no happen will not get the same because the magnetic field no have te same direction of force and therefore.I try to perform a simple experiment to levitate an object of iron trying to find a balance so that this does not fall, I try to study the magnetic force.
I did not try it with this setup, but I do have some ferromagnetic fluid. I do not think it will levitate in this setup since it will not generate the strong magnetic field required to sense its position. It is possible, however, to coat a magnet with a ferromagnetic fluid and make it levitate like that.
if you have another set up on the lower side of the top one could you control pull? or would the lower one compansate more pull with gravity? i also noticed that the coin was spinning, is this because of coiling or is it because of "un-evenness if you will" of the coin being used? it's just too interesting to not ask questions....
I am not quite sure if I understand your first question correctly but it is possible to use more than one coil to achieve better control. The levitating magnet is probably spinning because of the "un-evenness" both in coil and levitating magnet as you mentioned. Thank you.
Perpetual motion is impossible (within our current understanding of the laws of physics) as it would violate the laws of thermodynamics. Thank you for your generous offer though.
@skydiverangel it shouldnt in space, the temperture of space should act vey well with YBCO, and if matter is proved one day to gain mass at increased velocity, a perpetual velocity from increased mass squared created by an external gravitational effect, e2 x v/c ive asked the physics guys to do the math form me,but ive not a cat in hells chance...any takers? lol its worth a faster than c Nobel prize. :)
If the electromagnet is powerful enough, it can levitate a human being. However, this would not be due to the principle used in this video but it would be due to fact that a human body contains a lot of water and water is a diamagnetic substance.
I wonder if this could have practical use. Like for instance a floating pen support. You put the pencil (which has a magnet inside) on a support like the coil but in a box and you have a floating pen support for offices. Would look pretty great !!

No, it will not. It will only reduce the current through the electromagnet to reduce the magnetic force on the levitating magnet. The system in our "Rapid Control Prototyping Platform for Matlab and Simulink: Magnetic Levitation Control" video, on the other hand, can do this by reversing the current through the electromagnet. The repulsive force is very strong.
@skydiverangel Thank you - on your site there is a nice electromagnet under components and an NIB magnet above it on the list. Does the E magnet have an iron/metallic core? And without power to the coil could the NIB magnet latch to the iron core? And then could the coil receive power and the polarity of the coil be made to strongly repulse the NIB magnet?
Thank you for the positive feedback. The electromagnet has a ferrite core, and so the permanent magnet is attracted to it even when the power is off. The repulsive force generated by the electromagnet is not strong enough to overcome the attractive force between the magnet and ferrite core to propel the magnet into the air (unless a very large current is pulsed through the coil).
I invented a breakthrough energy source that contradicts the law of energy conservation. I have a PROOF that there are electrodynamic phenomena that contradict the law of energy conservation. I am looking for $300 000 for a prototype and for $3M for patents. Making a 6 kW generator will cost $1200 in mass production, value of energy produced yearly $5400.
@skydiverangel I have a theoretical and also experimental PROOF that there are electrodynamic phenomena which contradict the law of energy conservation. If you know Maxwell's equations, you should be able to understand it. My e-mail address is in my contact box.
Thank you for your reply. I am quite familiar with the Maxwell equations. However, I still do not think there is anything in these equations that contradicts the law of conservation of energy. If you believe that your claim is true, then publish it in a scientific journal. I am sure you will be getting the Nobel Prize in Physics.
@skydiverangel The fact that it is possible to break the law of conservation of energy was known to top physicists since 1861, when Maxwell published his equations. But it is a well kept secret. My e-mail address is in my contact box - send me an e-mail. and I will send you the proof.
@henrykay01 mind if you draw out a proof, and publish it on your youtube? id like to take a look at it, if it is a secret, show me a proof and ill look into maxwells law. and if you got that 6M, i heard obama is into new types of energy :) if you can get a good proof or at least a blueprint of this prototype,send it out to a few people, make copies, and TELL THE KIDS WITHOUT COLLEGE PHYSICS THAT THEY DONT DESERVE MODERN WARFARE!!!
The electromagnetic levitation system is available as a kit or fully assembled unit. Please visit the link in the description (zeltom.com) for more information. The mathematical model of the system and the parts list are also available on this page.
@skydiverangel Hey you still can used the same device in it same from, " however you would have to broadcast the magnetic filed by a carrier frequency wave, thus giving you greater flexibility to target most objects "and move them in many other direction, furthermore as it stands, ( you have a signal one directional filed of electromagnetic energy flowing and it's stabilized, :However I can say at this point is try broadcast the electromagnetism of the field energy.
Thank you. The controller has two main parts: (1) a nonlinear compensator for the sensor, and (2) a state-space based robust controller. A PD or PID controller together with a nonlinear compensation may also be used.
I am not sure whether we can call the generated magnetic field strong or not but we have a manufactured version of this device that works with 7.5 V, 0.125 A (approximately 1 W, 0.45 W of this is consumed by the microcontroller and 0.3 W of this is consumed by the voltage regulator). The coil is a super-coil but definitely not a superconductor coil (unless we discovered accidentally room temperature superconductivity).
All the forces involved here are conservative and if the levitating magnet is suspended still, it does not consume any power. The coil consumes approximately 0.18 W (mainly due to its internal resistance).
Is there a reason that a PID controller would be a poor choice for controlling the electromagnet? A PID seems like it could achieve higher speeds and use far less power.
The high frequency gain of a PID controller grows without bound. Thus, it amplifies the sensor noise. The controller used here is a state-space based controller but a PID or PD controller may also be used. The power consumption is mainly determined by the gap distance.
The force applied by the electromagnet is controlled based on the vertical position of the levitating magnet to balance its weight. The position of the levitating magnet is sensed by a Hall effect sensor. This is a standard and well-studied system in control theory. Of course, you can do it. If you have any questions, please email me. You may also consider our kit at zeltom(dot)com.
Do you have any Idea about Bose Active Suspension system? It uses the same principle of your setup here, what am wondering about is how much power do we need to suspend a mass of about 1000lbs on the air? :)
I do not know the specific details of their system. I read its description from their web page and it seems that it is just another active suspension system. I do not think it is based on the same principle. It uses the linear motors to apply a force to counter the external disturbances caused by the road surface. The maglev trains use the same principle. It is possible to levitate 1000 lb with little power (exact amount depends on the geometry of the system) using permanent magnets.
It isn't fake, idiot. I bought one of their magnetic levitation kits and it's working perfectly. This is one of the best magnetic levitation systems that I've ever seen. If I were you, I wouldn't open my mouth for things that I have no idea about.
Wonderful design. I studied your design a good bit and it was actually very important in convincing me that digital control can be used with good results.
I have many questions:
Do you use frequency compensation between your hall effect sensor and your micro's input?
What is your ADC sample rate?
I take it your electromagnet is just a large ferrite inductor? Where did you buy it?
Have you considered building a more complex, possibly repulsive controller?
1. I used a simple lowpass filter in this system but decided not to use it in my later designs to get rid of the delay.
2. The sampling rate is about 8 kHz.
3. As you have guessed, it is just a ferrite inductor. I could not find a suitable coil and wound that coil by hand. We are now using custom coils supplied by a manufacturer.
4. We have done some work on repulsive system. It is not robust enough yet and we are still working on it.
Thank you for your patience and sorry for the unexpected delay. They will be available either later this week or at the latest the first week of January. Please visit zeltom(dot)com for updates.
Oh, in that case, I do not know the answer to your question, as it is out of my area of expertise. However, I do not believe that this technology could be used for that purpose.
It is possible to increase the distance a little further but the maximum achievable distance is inherently limited by the force applied by the electromagnet and the resolution of the sensor.
your project seems to me amazing. I am of Mexico. it would want to know if you have the diagram of the circuit., since I want to make one equal, is that I am beginning with this of the circuits. thank you very much of all heart
Unfortunately, I cannot disclose the circuit diagram since a manufactured version is commercially available as a kit or fully assembled unit. Please check out zeltom(dot)com for more info.
According to Wikipedia, levitation (from Latin levitas "lightness") is the process by which an object is suspended against gravity, in a stable position, without physical contact. Thus, electromagnetic levitation is the appropriate terminology. This is also the standard terminology used in the (control) literature.
No, it does not spin. For the magnet to spin, there must be a tangential force acting on the magnet and such a tangential force can be the result of a radial current in the magnet. Thank you for the links. I watched both videos.

If you believe that your claim is true, then publish it in a scientific journal. I am sure you will be getting the Nobel Prize in Physics.
skydiverangel 1 year ago
@skydiverangel The fact that it is possible to break the law of conservation of energy was known to top physicists since 1861, when Maxwell published his equations. But it is a well kept secret. My e-mail address is in my contact box - send me an e-mail. and I will send you the proof.

@skydiverangel This is a SECRET, no physics journal will publish it.

@henrykay01 mind if you draw out a proof, and publish it on your youtube? id like to take a look at it, if it is a secret, show me a proof and ill look into maxwells law. and if you got that 6M, i heard obama is into new types of energy :) if you can get a good proof or at least a blueprint of this prototype,send it out to a few people, make copies, and TELL THE KIDS WITHOUT COLLEGE PHYSICS THAT THEY DONT DESERVE MODERN WARFARE!!!

The electromagnetic levitation system is available as a kit or fully assembled unit. Please visit the link in the description (zeltom.com) for more information. The mathematical model of the system and the parts list are also available on this page.

@felsn
Yes. It is possible to control the levitating magnet up, down, left and right but this
requires more than one electromagnet.

@skydiverangel Hey you still can used the same device in it same from, " however you would have to broadcast the magnetic filed by a carrier frequency wave, thus giving you greater flexibility to target most objects "and move them in many other direction, furthermore as it stands, ( you have a signal one directional filed of electromagnetic energy flowing and it's stabilized, :However I can say at this point is try broadcast the electromagnetism of the field energy.

so the electromagnetic field does not interfere with the hall effect sensor measurement? Or does the dspic account for the interference?
jpmorgan187 1 year ago
@jpmorgan187
Thank you very much.
The Hall effect sensor not only measures the magnetic field of the
levitating magnet but it also measures the magnetic field
generated by the electromagnet. Our control algorithm takes care of the effect of the magnetic field generated by the electromagnet.

@skydiverangel
very cool. Is it a PID controller?
jpmorgan187 1 year ago
@jpmorgan187
Thank you. The controller has two main parts: (1) a nonlinear compensator for the sensor, and (2) a state-space based robust controller. A PD or PID controller together with a nonlinear compensation may also be used.

@skydiverangel
how can you make such a powerful magnetic field with 1.5W (5V*0.3A)? Is the coil a superconductor material? ...i don't get it...
How is the magnet that is so powerful that can attach it self to a small field?
molinobeer 1 year ago
@molinobeer
Thank you very much for your questions.
I am not sure whether we can call the generated magnetic field strong or not but we have a manufactured version of this device that works with 7.5 V, 0.125 A (approximately 1 W, 0.45 W of this is consumed by the microcontroller and 0.3 W of this is consumed by the voltage regulator). The coil is a super-coil but definitely not a superconductor coil (unless we discovered accidentally room temperature superconductivity).
skydiverangel 1 year ago
@molinobeer
All the forces involved here are conservative and if the levitating magnet is suspended still, it does not consume any power. The coil consumes approximately 0.18 W (mainly due to its internal resistance).

Is a regular electromagent reversible?
roboman79 1 year ago
@roboman79
Yes, it is reversible (in the sense that its "magnetic polarity" will be reversed if the current through it is reversed).
skydiverangel 1 year ago
Is there a reason that a PID controller would be a poor choice for controlling the electromagnet? A PID seems like it could achieve higher speeds and use far less power.
Chironshands 1 year ago
@Chironshands
The high frequency gain of a PID controller grows without bound. Thus, it amplifies the sensor noise. The controller used here is a state-space based controller but a PID or PD controller may also be used. The power consumption is mainly determined by the gap distance.

geof0922 2 years ago
@geof0922
The force applied by the electromagnet is controlled based on the vertical position of the levitating magnet to balance its weight. The position of the levitating magnet is sensed by a Hall effect sensor. This is a standard and well-studied system in control theory. Of course, you can do it. If you have any questions, please email me. You may also consider our kit at zeltom(dot)com.

Do you have any Idea about Bose Active Suspension system? It uses the same principle of your setup here, what am wondering about is how much power do we need to suspend a mass of about 1000lbs on the air? :)
Kuwaiti27 2 years ago
@Kuwaiti27
I do not know the specific details of their system. I read its description from their web page and it seems that it is just another active suspension system. I do not think it is based on the same principle. It uses the linear motors to apply a force to counter the external disturbances caused by the road surface. The maglev trains use the same principle. It is possible to levitate 1000 lb with little power (exact amount depends on the geometry of the system) using permanent magnets.

The force applied by the electromagnet is adjusted based on the vertical position of the levitating magnet to balance its weight.
skydiverangel 2 years ago
Wonderful design. I studied your design a good bit and it was actually very important in convincing me that digital control can be used with good results.
I have many questions:
Do you use frequency compensation between your hall effect sensor and your micro's input?
What is your ADC sample rate?
I take it your electromagnet is just a large ferrite inductor? Where did you buy it?
Have you considered building a more complex, possibly repulsive controller?
cr99991 2 years ago
@cr99991
Thank you very much. I highly value your opinion.
1. I used a simple lowpass filter in this system but decided not to use it in my later designs to get rid of the delay.
2. The sampling rate is about 8 kHz.
3. As you have guessed, it is just a ferrite inductor. I could not find a suitable coil and wound that coil by hand. We are now using custom coils supplied by a manufacturer.
4. We have done some work on repulsive system. It is not robust enough yet and we are still working on it.

tonyrosam 2 years ago
@tonyrosam
It is possible to increase the distance a little further but the maximum achievable distance is inherently limited by the force applied by the electromagnet and the resolution of the sensor.

In this situation I would say it as electromagnetic attraction rather than electromagnetic levitation. Correct me if I am wrong.
TzerMaan 2 years ago
According to Wikipedia, levitation (from Latin levitas "lightness") is the process by which an object is suspended against gravity, in a stable position, without physical contact. Thus, electromagnetic levitation is the appropriate terminology. This is also the standard terminology used in the (control) literature.

Does the magnet spin while being levitated?
Please check out the work of John Searl.
Magnetic Levitation by eddy current
watch?v=xSvOX0gzZxQ
SEG voltage controlled demo
watch?v=z8qvSNkiB9M&NR=1&feature=fvwp
The demo only displays 200 rpm.
Once the device reaches 590 rpm, the eddy currents take effect and the device lifts off.
SearlSolution,com

TheRealVerbz 2 years ago
No, it does not spin. For the magnet to spin, there must be a tangential force acting on the magnet and such a tangential force can be the result of a radial current in the magnet. Thank you for the links. I watched both videos.
