The Maic UFO

The above video shows how a top can float in midair.

In order to achieve this, you have to fulfill several conditions. The first condition is to get the correct weight of the top. You might have to try several times. Why do you need the correct weight? the following diagram will explain it.

This is how the Magic UFO works. The magnetic repulsions force and the weight and gravity acting on the top must be equal. If the magnetic repulsion force is greater than the weight and gravity acting on the top, then the top would fly away. If it is the other way round, the top would not be able to float up.

Another important condition to fulfill would be the balance of the magnetic plate. It is somewhat the same logic as the first condition. If the plate is tilted on side of the magnetic repulsion force would not be equal and thus the top would not be able to fly properly.

I have drawn this picture and hopefully it can help you understand better. The orange part is where the magnetic repulsion force comes from. As you can see, it is in a round shape. As the force acting on the top is in a round shape, it sort of supports the top and keeps it in position- the middle. Thus if we tilt the plate, we can say that the repulsion acting on different parts of the top are different.

If you have the chance, you should try it one day. It is really fun.
