Is a diamagnetic levitation engine possible?

In summary, the conversation revolved around the possibility of levitating a vehicle using a large magnet and the amount of energy it would require. However, it was pointed out that levitation depends on the proximity of two magnets and would not work over a lake. The idea was also dismissed due to the fact that the ground is not magnetic and only magnets can push magnets. The conversation concluded by encouraging the individual to continue learning about STEM subjects and the limitations of such an idea.

I recently saw the video of the frog being levitated with a big magnet. Would it be possible to flip the magnet over and use it to levitate a vehicle? How much energy would it take to levitate, say, a 1000kg vehicle above a dry lakebed?

:welcome:

Please provide a link to the frog video. PF rules require that you cite your source when making statements like that.

Yes, see https://en.wikipedia.org/wiki/Maglev Maglev trains are already in operation in several places.

But levitation depends on the proximity of two magnets. It wouldn't work over a lake.

All materials have at least some magnetic properties, or the frog wouldn’t levitate. And I don’t mean water, I meant the salt flats like in Utah.

Have you ever seen a junkyard?

But the magnet would be on the vehicle and repel the ground below it.

I gave you that answer in post #2.

It would not levitate due to soil/sand not being magnetic, magnets can only push magnets

Not true.

Please keep on learning about STEM subjects, and asking questions. That's a great thing, and it will lead you on a good path in life.

Unfortunately this idea of yours in this thread will not work. If it could work, it would be used widely for transportation already. The maglev train example mentioned earlier is the closest to what you are thinking about. Please study the Relevant Concepts and Equations for Maglev transportation linked to earlier, and if you have specific questions about that reading, start a new thread with links to that reading and your questions. Keep on learning! :smile:

Oops, I thought this was already posted in this thread Maybe it was from a different recent similar thread. In any case, here is the Maglev link:

What is a diamagnetic levitation engine?

A diamagnetic levitation engine is a type of propulsion system that uses the repulsive force between magnets and diamagnetic materials to create lift and movement.

How does a diamagnetic levitation engine work?

A diamagnetic levitation engine works by using a superconductor to create a strong magnetic field, which interacts with the magnetic fields of permanent magnets to create levitation and propulsion.

Is a diamagnetic levitation engine possible?

Yes, a diamagnetic levitation engine is possible and has been successfully demonstrated in laboratory settings. However, it is not yet a practical means of transportation due to the high cost and technical challenges involved in creating and maintaining the necessary conditions.

What are the potential applications of a diamagnetic levitation engine?

A diamagnetic levitation engine has the potential to be used for transportation systems, such as high-speed trains or maglev vehicles, as well as for space propulsion systems due to its ability to operate in a vacuum environment.

What are the limitations of a diamagnetic levitation engine?

The main limitations of a diamagnetic levitation engine are the high cost of materials and energy required for superconductivity, as well as the technical challenges of maintaining stable and controlled movement. Additionally, the engine is currently limited to low speeds and cannot operate on rough or uneven surfaces.
