How does quantum mechanics explain why an electron spins?

Question

isnt the spin of the electron that causes magnetism?

Answer 1

Quantum mechanics doesnt explain this, it is in fact not true. There is no such thing as a spinning electron, because an electron has no volume, it cannot spin. There is a quantummechanical property called spin though, but this is not the physicly spinning of a particle.

Answer 2

an elctron acts as if it spins because one of the ground assumptions of quamtun mechanics is that particles have differant properties that make one distinct from others of the same kind. One of the asigned properties is spin but a rigidly defined spin that has a quantified value and cannot be a half way value. it was assigned because of the pauli exclution princi;le, it says that two of the same particles cannot share an orbital. therfore there has to be a difference and one of the differences more closely resembles spin but it isnt macroscopic spin. We must not confuse a model for the the thing being modeled. electron spin is a concrete item and everiday spin is nore related to statistical conditions (the vector sum of all individual spins). Oh yeah by the way in orther for matter to exist rules had to be violated (Symmetry) We know that synetry was violated because we are here.- Oh well thats the anthropic principle, a bone of contention. just be happy and spin

Answer 3

Quantum mechanics does not say the electron (or any subatomic particle) spins.

However, the spin is simply a state of the particle, wherin it occupies one of two possibilities. The math here is very complex, involving matrix analysis. End result, 2 particles cannot be in the same exact state, with respect to all quantum-mechanical states (spin is just one of them).

It is easiest to visualize these staes as physical events, and the spin here is best illustrated as the particle "spinning" in one direction or another. However, do not take these images as true.

Answer 4

in accordance to the de Broglie postulate, any particle has an linked wave with a wavelength given with the aid of h / mv., the position h is the Planck's consistent, m is the mass and v is the speed. The sq. of the wave amplitude for a given position is proportional to the probability of looking the particle at that position. because of this one can't communicate about a properly defined radius for an electron orbiting a nucleus.

Answer 5

no
actually quantum mechanics dont explain a lot of things thats what made me post this question
