Except for the neodymium magnet I've tried to use materials that you can find in a good Step 3: Build the Magnetic Top. Finally you have the magnetic top. At the end of the previous steps the weight of the.
This instructable explains how you can build your own top hovering in the air like a UFO. Did you ever try to levitate a magnet with the help of bunch of other magnets? It seems very easy: since magnets can repel each other you probably can put a bunch of magnets in circle so they equally push the other magnet towards the center of the mae. Or maybe even build a sphere made of magnets that would suspend another magnet in the center.
In fact back in British mathematician Samuel Earnshaw proved that it is in fact impossible to suspend a regular magnet in space with the sole help of other regular magnets statically placed around it. So it is impossible to suspend a magnet in space using just bunch of other magnets. But take a look at the video. There is a large ring ceramic magnet and another magnet which is also a top. And if I carefully spin the second magnet above the first one it will indeed hang in the air.
How is that possible?! This is gonna be cool! It is actually very easy to build this levitating top. Below you can find the exact bill of materials I used. To take a ceramic magnet from the cup Magnettic put it in hot water for 20 minutes to loosen the glue, then pried with mmm whatcha say official music video screw driver and pulled out like it is shown in the video and explained further in this instructable step 6.
In fact for this exact setup I used only one washer with 32mm in diameter and 1. All other brass washers were not necessary in the final version. I used a 68mm tall and mm in diameter container 12 1. The plastic container is required to protect the magnets from each other.
No matter how careful you are the top will keep falling down and eventually hitting the magnet. Each time this is happening small sharp chips will fall off the magnets. Besides covering your work place with potentially dangerous to electronics magnetic dust they also ruin all your efforts to fine-tune the top.
Another function of the plastic container is to adjust the distance between the top and the large magnet. As you can see in the video this distance is very critical for successful initial legitating. The top of the container plus the sheet should be very close to the position where the large magnet stops repelling the top and starts attracting it. In fact you can even move the small magnet along the top stem to calibrate this distance precisely.
If you try to spin the top on top of properly lvitating container it will actually stabilize itself for seconds and spin absolutely straight. In order to extract the magnet from the cup I soaked it in hot water for approximately 20 minutes, then used a screwdriver to pry and remove the magnet.
Use the dowel to turn the small disk magnet into a top. I cut approximately how to make a magnetic levitating top off the dowel and polished one end with sanding paper to give it something like parabolic shape and make it smoother.
Make sure you put a non-magnetic spacer between the top and the scale, otherwise metal parts of the scale will attract the magnet and the measured weight will be inaccurate. See the video for details. Since I'm using two smaller magnets for the base instead of one large this is the step where I stack them. Do not just put one hod top of another -- you will damage both the magnets and how to make a magnetic levitating top fingers.
Instead, slide the top magnet on top of the other one. You can skip this step if you have one large magnet. Cover the large magnet with the container, put the aluminum sheet on top and your base is ready.
Now is the time for a few steps with a lot of levitxting and no pictures. It's just really difficult magnetix explain dynamic problems with static text, so check the video in step 1 to see how this works.
Put a flat sheet made of non-magnetic material on top of the plastic container and try spinning the top. Remove the cover and slowly lower the top on it. Flip the large magnet over. Put the cover back. Reduce the distance from the top to the large magnet by lifting the large magnet. Washers and bottle cups will help you to lift the large magnet.
In this case it falls and tumbles immediately after you release it. You need to increase the distance between the top and the magnet. You can do it by lifting the plastic container on washers of bottle cups, for instance. The perfect position for the top is slightly below that point when big magnet stops repelling the top and starts attracting. Adjust the mak of the magnet under the plastic container so the top is located exactly at this position when you try to spin it.
You can also move the small magnet alone the top stem to fine-tune the setup. Please note that in this position you might need to push the top down slightly while spinning it. If you find this inconvenient feel free to reduce the distance between the magnets a bit more. In fact one more thing can go wrong with spinning: the speed.
In how to make a magnetic levitating top start from the slow side and keep increasing the what color paint goes with orange brick until you reach the maximum speed after which the top goes crazy. Besides just the initial spinning the spin-stabilized magnetic levitation only works at speeds between and RPM revolutions per minute. Once you positioned the top properly it should be able to spin stably on sheet.
In fact if you are lucky and patient you can position it mabnetic a point at which it will self-stabilize itself. Even if you spin it not too well it will will eventually straighten up. Oh, and one more important thing is where you start spinning - it should happen exactly above the center of the large magnet, otherwise the small magnet how to make unpasteurized sauerkraut tumble and not spin at all.
Slowly and steadily lift the sheet up maintaining the level. This means that the top is too light and gravitation force is not enough to compensate the magnetic repulsion force. Add some weight to the top. Brass washers are the heaviest ones, rubber ones are lighter. You tp also sand the washers to adjust their weight. The top is too heavy and magnetic repulsion force is not enough to compensate the gravitation. Remove a washer from the top. If this is the last washer then replace it with the lighter one.
After adding and removing washers to the top you should reach a point when the top takes off the sheet, tries to levitate on how to apply for a fha loan in florida of the magnet but after half w second it flies away. Pretty much like a ball rolls down the hill our top rolls down the magnetic hill.
You need to keep adjusting the big magnet level until the top starts flying away in different directions. Also make sure that the big magnet resides on a firm surface like a table. The truth is you probably will need to do phase 2 and 3 simultaneously as it it sometimes unclear why the top flies away so fast. Levitatihg could be both the magnetic field level and the weight.
Again, you can put washers or something else thick and preferrably non-magnetic underneath the large magnet in order to level it. You can even use an Arduino as a hw if you want to involve how to download car designing software for free microcontroller in this project :. At this point almost everything is working great except the top is still unable to levitate as it flies away.
Time for the phase 4: final fine-tuning. You need to add small weights to the top. The fine adjustment weights are in fact so small that washers do not work anymore. The best candidate for adjusting the weight is electric tape. Keep sticking small pieces of electric tape until the top stops flying away. Using electric tape you can build how to make a magnetic levitating top top that will levitate for a minute or two. One problem with it is bad aerodynamics of tape strips.
Once you figured out the final magetic it is probably a good idea to replace the take with a bunch of brass washers. This will increase the flight hkw to up to 5 minutes well, minutes is a more realistic time. One more important thing is that the entire top should be very firm.
No pieces what is an xmp file be unsecured or wobbly. Use crazy glue if necessary, but make it feel like a one solid piece. Do it quickly! The problem is that the effect is very unstable.
Once the temperature in the room changes -- you will need to redu fine tuning. Humidity changed? Same thing. Someone put scissors nearby? Adjust it again. Or move the scissors away, whatever is easier : The fact this type of magnetic levitation is so unstable greatly reduces its usability.

This time, we learn about how the gyroscopic forces of a magnet spinning like a top can temporarily overcome the stability issues and levitate for several minutes. The floating magnet tends to fall to the side, or flip around to attract to the base magnet.
To make levitation work, you need to add stability. In spin stabilized magnetic levitation, the gyroscopic forces of a spinning top seem to do the trick. Note: Riding a bike is easier than getting one of these tops to spin. Even with a perfect setup, it takes a lot of effort and persistence to get it balanced just right.
This phenomenon was originally discovered in the s. It was sold as a toy, most popularly in the mid to late s. We had to try one out for ourselves. As we suspected, it used weaker, old-style ceramic magnets in both the base and the spinning top. There are several different adjustments to get the balance just right. It can be hard to figure out which control to adjust, and even which way to change it!
If you want to try this sort of thing yourself, be prepared for a long period of experimentation before getting it working. The sweet spot of stability is small and hard to find. A big ring magnet serves as the stationary, base magnet in these devices. The one's we've seen use a large ceramic ring magnet to provide the repelling force.
They can be as large as inches in diameter. In the example we bought, the base magnet was actually a simple block shape, but it had an area at the center that was not magnetized. It seems to perform much like a ring magnet. The big ones we do have are much too powerful for this spinning top setup. It should be thin, and not have too much magnet material. To prototype this quickly, we made a compromise. Instead of constructing a big, thin, fragile neodymium ring magnet, we mimicked a big thin ring using a series of magnets arranged in a ring pattern.
With a series of disc magnets arranged with all of their north poles facing upward, the array mimics a single ring magnet. There might be some differences in the field very close to the magnets, but up above them where the top floats, we figured it should be a close enough approximation.
Neodymium magnets repel each other in this ring-like configuration, so we came up with a few ways of holding them in place. We 3D printed a few bases. We drilled holes in a wood block to hold the magnets.
We even tried simply sticking them to a sheet of steel and taping them in place. The body of the top shown above is a plastic, 3D printed part. Plastic or brass washers provided the adjustable ballast weight.
They are set into drilled holes in a block of wood, all of them with their north poles facing up. If you can 3D print, here is a link to Thingiverse to find our models for the top and the base. We've spent way too many evening hours strugging with this one! In the spirit of Mythbusters, it seems fitting to take all of this success and then pump it up a notch for the finale.
A good conclusion might take it to the extreme; go big or go home. We doubled the scale of our earlier success and built a base with thirteen 1 inch diameter DX04B-N52 magnets. Doubling the size of the top as well, we chose the RX8C4 ring magnet, a powerful magnet indeed. We hoped to include a short description about how spin stabilized magnetic levitation actually works. Without diving too deep into incomprehensible physics equations, we wanted to share the hows and whys in plain language.
The more we learned, however, the more difficult this became. We figured there ought to be some comparison with the stability of a bicycle, which everyone ought to understand. What we found further confounded us.
Bikes self-steer to stay upright because the front wheel contacts the ground behind where the axis of the rotating handlebars points. So much for that comparison.
