Spin particles not in a magnetic field

In summary, spin particles are fundamental particles with an intrinsic property called spin, which is a quantum mechanical property. This spin property is not present in normal particles and can take on discrete values. Spin is important in understanding particles and is a key component in physical theories. Spin particles do not always need to be in a magnetic field, but a magnetic field can affect their behavior. Spin particles can also be in a superposition state, existing in multiple states simultaneously.

If spin particles are in [itex]\vec{B} = 0[/itex], then is it impossible to determine their magnetic moment at a given time given any investigative method?

I think you could use something like Aharonov-Bohm: create a region where B is 0 but A is not and interfere. Alternatively, you could accelerate these particles and measure their electric polarization (a moving magnetization becomes a polarization)
 

Related to Spin particles not in a magnetic field

1. What are spin particles?

Spin particles are fundamental particles that have an intrinsic property called spin, which is a measure of their angular momentum. This spin property is a quantum mechanical property and is unrelated to the physical rotation of the particle.

2. How are spin particles different from normal particles?

Spin particles have an additional quantum property called spin, which is not present in normal particles. This spin property can take on discrete values, such as 1/2 or 1, and it affects how the particle interacts with other particles and fields.

3. Why is spin important in understanding particles?

Spin is important because it is a fundamental quantum property of particles that affects their behavior and interactions with other particles and fields. It is also a key component in many physical theories, such as quantum mechanics and the Standard Model of particle physics.

4. Do spin particles always need to be in a magnetic field?

No, spin particles do not always need to be in a magnetic field. The spin property is an intrinsic property of the particle and is not dependent on external factors. However, a magnetic field can affect the behavior of spin particles and can be used to manipulate them in experiments.

5. Can spin particles be in a superposition state?

Yes, spin particles can be in a superposition state, which means they exist in multiple states simultaneously. This is a fundamental aspect of quantum mechanics and has been experimentally verified in spin particles, such as electrons and protons.
