LEVITRON HOMEMADE, Here I present a tutorial on how to do it. This curious home experiment consists of a base made with large magnets and a top with a small magnet. Simple, right?

0:00 Intro
Now I explain to you step by step how to do it:
0:15 How to make the Magnet Base?
You will need at least 3 large magnets with a recommended diameter of 10 cm.
0:41 How to attach the magnet base?
We will carefully place them on top of each other in order of magnetic strength.
How to measure the magnetic force of a magnet?
You can measure by bringing an iron bar closer to each magnet and you will easily notice which magnet adheres stronger than another, and so you can organize it in order of magnetic power.
1:01 How to make a Levitron spinning top?
Making a spinning top depends on your creativity, as there are many ways to do it. But this time, I'll give you an idea. First, we look for a bottle cap called a "take everything." Then, we take the sliding part of the lid, and we practically have the heart of the top. Next, we need a small magnet, about 3 cm in size, which we attach to the sliding part of the lid. Finally, we need the axis of the spinning top, for which we find an "eyeliner" pencil and cut it 4 to 5 cm long. The good thing about this pencil is that it has a convex end that allows us to rotate easily. That's all! Then, we join all the pieces, and we will have our flying top.
Two possible obstacles:
3:41 - Very light top: This obstacle occurs when the top floats very quickly after being lifted, jumps several times in the air and ends up being ejected to the side of the base.
Solution: Add weight to the top using washers, rubber gaskets, or something similar that fits the shaft of the top. As you add weight, keep testing until it stabilizes and levitates.
3:58 - Very heavy top: This obstacle occurs when you lift the top and it does not come off. If you manage to take off, you will quickly fall towards the center of the base due to the excess weight on the top.
Solution: Reduce the weight of the top by removing one or more washers you installed. As you reduce the weight, keep testing until you feel that the top can provide the necessary momentum to levitate, which would confirm that it is lighter.

Tips:
- Practice spinning the top on a smooth, flat surface, such as a table, without the magnetic base, since in 80% of cases it is very difficult to spin it for the first time with the magnetic base underneath.
- A trick to levitate well is to slowly lift the top and concentrate on keeping it level and spinning smoothly without vibrations. This will make the top levitate well and last as long as possible.
- Place pieces of fabric in the center of the magnet base to cushion the fall of the top when it falls towards the center of the base.
My Story with the Levitron:
I started trying this Home Experiment when I was 14, it took me about two weeks of a lot of patience and I finally did it. But I didn't realize that I had done the first Levitron Experiment in my country "Peru". I was happy about it, so I uploaded it to this video platform to show everyone that it is possible. Soon many people from my city "Lima" contacted me to help them do this famous but somewhat complicated experiment.
Currently, I am 24 years old and it has been a decade. I made this video again to explain more details to the public on how to make a Levitron.
Frequent questions:
How long does magnetic levitation last?
Homemade levitrons last an average of 2 to 3 mins.
Why does the levitron fall?
Over time, they lose their turning force due to air friction.
Why does the top levitate?
Due to the repulsion of the magnets of the base with that of the top and the “gyroscope effect” that occurs when the magnet of the top rotates. If the magnet were static, it would not levitate.
Where can I get the large magnets?
You can get them from old speakers, hardware stores, second-hand places, or recyclers. You would have to go to the metal areas where they are most likely to be found.
Where can I get the small magnets?
You can extract them from old headphones, small speakers, or go to places where second-hand items are sold and go to the metal area.
What type of magnet do I use?
They are "ferrite" magnets, also called "ceramic magnets."
Does it work with a single magnet on the base?
Yes, but from my experience using ferrite magnets, with a single magnet at the base, it will levitate at a low altitude and I have even noticed that they last a short time levitating.
How many revolutions per second does it rotate during levitation?
20 to 30 rotations
How high does the top levitate?
It depends on the level of repulsion of the base magnet with the top magnet.
