(Apologies for a basic question) Do charged particles always have spin ? Maybe a better question is, are charge and spin always associated ?
And photons!mfb said:We know uncharged elementary particles with spin - neutrinos.
Yes, all charged particles have spin. Spin is an intrinsic property of particles, meaning it is a fundamental characteristic that cannot be changed or removed. This includes particles such as electrons, protons, and even more complex particles like atoms.
Yes, charged particles can have different spin values. Spin is quantized, meaning it can only take certain discrete values. The spin value of a particle is determined by its type and can range from 0 to 2 (in units of Planck's constant divided by 2π).
Spin affects the behavior of charged particles in several ways. For example, it can determine how a particle interacts with magnetic fields, how it scatters off other particles, and even how it contributes to the overall spin of a larger system.
No, spin is not the same as angular momentum. While both are related to rotational motion, spin is a property of particles, while angular momentum is a property of a system. Additionally, spin is quantized, while angular momentum can take on any value.
Yes, the spin of a charged particle can change. This can happen through interactions with other particles or through external forces, such as magnetic fields. However, the spin value itself cannot be altered, as it is a fundamental property of the particle.
