Please confirm magnetic levitating rotor

In summary, the conversation discussed the possibility of a video showing magnetic levitation being a trick. It was suggested that the magnets used in the video may have been taken from old speakers and arranged to work for the application. However, it was also mentioned that this is not an issue as magnets are still magnets and the phenomenon of magnetic levitation is real.

what do you think is this video real or is there a trick somekind ?

The static semi circle magnets look just off centre from the levitating disk shaped ones. If the semi circle ones have, say their north poles facing towards the axis of rotation and the disk magnets are axially polarised and have their north poles facing inwards towards each other, then the semi circle ones would repel both of them in opposite directions due to them being slightly closer together than the disk ones are, this would create an equilibrium position in the axial direction. The semi circle magnets would also repel the disks vertically, this repulsion would be countered by the weight of the axle and disk magnets at some height, these two combined create a point of equilibrium where the axle can spin. Doesn't look like anything weird happening, you can buy toys that do the same thing.

No problem with that, they're still magnets. What are you thinking the issue is?

no I am ok there is no issue just at first I was a bit skeptical because of the video not the fact that magnetic levitation is a real phenomenon.
 

What is magnetic levitation?

Magnetic levitation is a method of suspending an object in the air using magnetic fields. This allows the object to float without any physical contact with its surroundings.

How does a magnetic levitating rotor work?

A magnetic levitating rotor works by using magnetic fields to create a force that counteracts gravity. This force keeps the rotor suspended in the air, allowing it to rotate without any physical contact with its base.

What are the benefits of a magnetic levitating rotor?

Magnetic levitating rotors have several benefits, including reduced friction, increased efficiency, and longer lifespan due to the lack of physical contact. They also have potential applications in transportation, energy production, and high-speed trains.

What materials are needed to create a magnetic levitating rotor?

To create a magnetic levitating rotor, you will need a strong permanent magnet and a magnetic material, such as a ferromagnetic metal or a superconductor. You will also need a power source to create the magnetic field.

What are some challenges in developing a magnetic levitating rotor?

One of the main challenges in developing a magnetic levitating rotor is overcoming the strong forces of gravity and friction. Additionally, the materials used must be able to maintain their magnetic properties at high temperatures and have a high strength-to-weight ratio.
