Spin mass in a vacuum, efficiency?

In summary, the conversation discusses the possibility of using a ball neo magnet to create a frictionless bearing by balancing it on other magnets and spinning it at high speeds in a vacuum box. The question is raised whether the magnet would spin indefinitely due to the lack of friction, but it is noted that there may still be a loss of energy due to the changing magnetic fields.

Hey guys I was wondering what would happen if:

took a ball neo magnet, balanced it on a few other magnets to basically make it a frictionless bearing. Then spin the ball magnet to 10k rpm. But do all this in a box that's a vacuum.

Would the neo ball magnet spin basically for a VERY long time since there is no or very little friction since it probably wouldn't be a 100% vacuum?

What if you could make the box be 100% vacuum, would it spin forever?

Air isn't the only source of friction. Even with a levitated magnet, its magnetic field will be changing relative to the magnetic fields it is being supported by. That is cause a loss of energy- i.e. friction.
 

What is spin mass in a vacuum?

Spin mass in a vacuum refers to the amount of rotational energy that a particle possesses in a vacuum environment. It is a measure of the particle's angular momentum and is a fundamental property of quantum particles.

What is the relationship between spin mass and efficiency?

There is no direct relationship between spin mass and efficiency. However, spin mass can affect the efficiency of certain processes, such as in quantum computing or particle accelerators, where the particles' spin can determine their behavior and interactions.

How is spin mass measured?

Spin mass is measured using a variety of techniques, including spectroscopy, scattering experiments, and magnetic resonance imaging. These methods allow scientists to observe the behavior of particles and calculate their spin mass.

Can spin mass be manipulated?

Yes, spin mass can be manipulated through various techniques such as applying magnetic fields, using lasers, or changing the temperature of the environment. This manipulation can alter the spin state of particles and affect their behavior.

What are the practical applications of studying spin mass in a vacuum?

Studying spin mass in a vacuum has various practical applications, including in quantum computing, materials science, and particle physics. It allows scientists to better understand the behavior of particles and develop new technologies and materials based on their spin properties.
