Nope, no Photoshop and no fishing line were used to make this picture, just 100% pure physics and some patience. This instructable explains how you can build your own top hovering in the air like a UFO.

Step 1: Video Overview

Some steps of this instructable are difficult to explain with plain text or even show with static pictures, so I encourage you to also check this video illustrating the build and tuning process. Sometimes it is better to see once than read a hundred times.

<p>in my magnetic levitation experiment the top keeps circling.....please suggest appropriate corrections or more details if required</p>
<p>how do I make a cake levitate on top of another cake top cake about 300g what type of magnets would I use</p>
I am doing a science fair project on levitation device. Got any tips?

Please help? I set 2 small glass candle jars with metal lids on TOP of my microwave and a few hours later the jars had mysteriously moved from the back to the front? This has happened numerous times, I push the jars to the back and a few hours later they have moved to the front. Could the magnetic field or magnetron be attracting the metal lids on the jars and causing them to move forward? Also when I line the jars up, I put the taller jar directly behind the smaller jar but when they move forward, the larger jar with the bigger metal lid, is setting side by side the smaller jar? Please help, my family thinks I'm going crazy! lol
<p>This may have nothing to do with magnetism. When the turntable in the oven is turning it causes vibrations. If the oven is not perfectly level the jars could just be sliding towards the back.</p>
A good source of strong donut magnets is a broken microwave. They all have two good magnets in them. Wrapping electrical tape around them makes them chip resistant and easier on your fingers.
TinmanMike, could the magnetic field in a microwave attract metal objects setting on top of the microwave and cause them to move toward the magnet or magnetic field?
The magnetic field would not pass through the steel housing of the microwave.
What if the microwave door wasn't closing good and allowing it to get thru? The fact that the larger jar with metal lid was pulled out from behind the smaller jar and then exactly lined up next to each other, tells me something with enough force pulled it out around the smaller jar? The larger jar also has a rusted star hanging down off of it, the smaller jar does not, only a steel lid. Am I totally off here?
Too bad my microwave is not broken yet :)<br>Thanks for the tape hint!
<p>What is the function of the metal plate? Can I use large magnets to levitate smaller magnets?</p>
<p>I'd assume this would be possible but does anyone know if I can duplicate this in smaller proportions? I need something I could hold in my hand (for cosplay reasons)</p>
<p>He said that you need to tune it quick. Will it be easy to take this to school for fair or will be hard to balance again. </p>
<p>no you cant rotate the base because the spinning top needs to be spinning to create it own balance otherwise it would stumble and fall down (Look up gyroscope experiments)</p>
<p>Would it be possible to rotate the base at the same rate and keep the object static?</p>
<p>thanks :)</p>
<p>can someone help me do this with only two magnets</p>
<p>heey ... can i use a normal metal and Magnetizes with an electric current ? as i want the electromagnetic theory to be a factor here .. </p><p>what are the Obstacles that would face me ?</p>
I was searching for this trick for a year.
<p>Hello ... WOnderful instructables. I'd like to know if the same can work with shoes? Can anyone make this? I'm not much into science but love experimenting such things. Levitation has been my favourite subject and fantasies me a lot. I was super excited to see HUVRBOARD has built this technology, but disappointed as they are not giving any info on selling such boards (atleast for now). Could you possibly make this technology in shoes and other accessories? Could you kindly teach a layman like me how to build it sitting at home (required materials)?</p>
<p>Hi mikhalchuk.That was a great instructable.You have helped me a lot through this.</p><p>This is probably going to be a weird question but is it possible to add a bit more complexity to it so as to differentiate it from the rest.You see I have a science fair coming up and i had decided to exhibit this loop hole in Earnshaw's theorem but one of the other students overheard my team discussing it and now they too are doing the same thing.</p><p>Anyways I really like your instructable and your explanation was suburb.Pls keep up the good work.</p>
Great work. Thanks.
Hook it up to the bottom of my state board...
i wanted to levitate something easily and found it here! thanks!
Can u use magnets different from what you used?
Hi, could you comment on Tom Shannon's magnetic sculpture relative to Earnshaw's theorem? <br>It stays in the air with static magnets and does not move. <br>You can see it on the video at 02:00. <br> <br>http://www.youtube.com/watch?v=OPA-rQyKeLY
Jussi, he clearly says he has it &quot;down to one tether&quot;, it is not static with magnets alone, you can see the tether in this picture: http://i.imgur.com/GYfwY2g.jpg or at 1:52 in the video as the focus is changing
i am just a beginner..i have a doubt.. <br>will it work if i rotate the base magnet (the one below using motor or smthing) and leave the small (levitating magnet) stationary.. will the small magnet levitate??
As you probably saw many times when playing with magnets, magnets push each other away if you try to bring together their like poles, for example, two north or two south poles. Similarly, the north pole of the external field will try to push away the &ldquo;north poles&rdquo; of magnetized atoms. The magnet used in magnetic levitation creates a very large magnetic field (about 100 to 1000 times larger than household magnets). In this field, all the atoms inside the frog act as very small magnets creating a field of about 2 Gauss .You may say that the frog is now built up of these tiny magnets all of which are repelled by the large magnet. The force, which is directed upwards, appears to be strong enough to compensate the force of gravity (directed downwards) that also acts on every single atom of the frog. So, the frog&rsquo;s atoms do not feel any force at all and the frog floats as if it were in a spacecraft.To levitate something the size of a human being it requires more powerful magnet. <br> <br>Source: http://thesecretsofscience.com/science-in-nature/magnetic-levitation/ <br> <br>
in soviet russia magnet repels you!<br>lol awesome video
aharner1, hard to believe but in the USA magnets also repel humans! :)<br><br>Human body is 60-70% water which is slightly diamagnetic. In theory human body even can levitate in strong enough magnetic field. In practice, though, it is not achievable with permanent magnets and mankind didn't build so strong electromagnet just yet. <br><br>There are electromagnets powerful enough to repel and levitate frogs and even mice.

Awesome accent.<br>
can we use any other magnets
Excellent instructable. I have been working on building a mechanical based clock utilizing magnetic energy in order to extend run times, as well as, general experiments. There is a lot more to magnetic energy than conventional science would have one believe. For every law of physics there IS a loophole -(remember - conventional science at one time said human flight was imppossible)- it simply takes a lot of time, effort, and energy to find it. I appreciate your very thourough explanation of the process you use and excellent instructions. Your command of the english language is very good. Keep up the good work and I intend to check out your other stuff. <br>Alton B.
Thank you AltonB! I'll keep working on my English too :)
So, if the temperature dropped or the humidity changed it would fall?
Unfortunately yes. In a controlled environment + vacuum it can spin and levitate for days, but in regular room conditions the effect lasts for a few minutes only.
Dude this is great! hope you do more.
Thanks Trooper555! I'm working on new stuff, hope to get it published soon.
Do stacked magnets generate a stronger magnetic field than one magnet? If not, could you replace the second magnet with any magnetically neutral spacer, like a piece of styrofoam or wood?
ericCycles, they do. The resulting magnet is less than twice as strong, but definitely much stronger than just one.<br>The spacer is also there - that's the primary function of the plastic container.
If you were to force them against each other, that effect may be attained. But not if you allow them to go the direction they want.
Glenn, you're right, thank you for the correction and clarification. BTW, for reference here are a few sources that claim the opposite (and they are wrong):<br><br>http://www.eng-tips.com/viewthread.cfm?qid=148854&amp;page=17<br>http://answers.yahoo.com/question/index?qid=20100228121105AAGhoeS<br><br>To my best understanding in this particular case stacking the magnets changes the configuration of the magnetic field, makes it &quot;more directional&quot; and increases its strength alone the axis. So to the top it seems like the stacked magnet is more powerful that single one. <br><br>Could you please comment if this is a correct guess? Definitely with one magnet this particular top won't hover, but it does levitate on top of the stack.<br><br>Thanks alot!
Stacking magnets is not always a solution. If you chain them long enough they will self-node, and fall apart at those node points.<br><br>The only real problem with this project is that the top is balanced on a point of UNSTABLE EQUILIBRIUM, i.e., the forces that are balanced are all trying to pull the top out of the &quot;sweet spot&quot; whereas a pendulum is and example of STABLE equilibrium because the combined forces keep drawing it back to the point of stability.<br><br>It looks like fun to try out, but I don't want to destroy any of the decent speakers that I have...
do you have a picture/thread for this &quot;pendulum&quot;? I've been working on one and would be interested to see what other results look like...<br><br>cheers, tom
Letting the magnets go the way they want when stacking them makes the fields larger because of overlap but not stronger. but if put in a direction against their &quot;wish&quot; they have a stronger field.
Sorry, mikhalchuk, But that is not correct. The sides that contact each other cancel out. You end up with a magnet of the same strength but double the size.
