Are there any experiments or theories about the relation between magnetic dipole moment orientation and velocity vector of free electrons?
WannabeNewton said:A free electron's dipole moment doesn't couple to its classical velocity for obvious reasons.
For accelerating electrons see Thomas precession.
carrz said:So are you saying that a single free electron traveling in a straight line with constant velocity, in absence of any external magnetic and electric fields, can have its magnetic spin dipole moment oriented in any arbitrary direction?
carrz said:I understand that only applies to bound electrons in atomic orbitals.
WannabeNewton said:Yes this should be entirely obvious. It's no different from saying you can prepare a system of torque-free and force-free gyroscopes in arbitrary directions. If I'm in the inertial rest frame of such a gyroscope then I can rotate it around at whim so as to have it point in any arbitrary direction I choose and the gyroscope will stay oriented that way because it is free.
Then you understand incorrectly. Did you even do what I asked and look up Thomas precession? You certainly do not yet know of its generality and where it actually comes from. There's no point in me explaining it when you have a wealth of resources online which can do so in depth.
Free electrons are electrons that are not bound to any specific atom or molecule and are able to move freely within a material.
Intrinsic spin magnetic dipole moment orientation refers to the orientation of the magnetic dipole moment, which is a measure of the strength of the magnetic field produced by an electron's spin. It is an intrinsic property of an electron that determines its behavior in a magnetic field.
Free electrons contribute to magnetism through their intrinsic spin magnetic dipole moment orientation. When a large number of free electrons are aligned in the same direction, they produce a magnetic field, which can lead to the formation of a permanent magnet.
Bound electrons are electrons that are tightly bound to an atom and are not able to move freely. Free electrons, on the other hand, are not bound to any specific atom and are able to move freely within a material.
The orientation of an electron's spin affects its properties in various ways. It determines its behavior in a magnetic field, contributes to the formation of permanent magnets, and can also impact the electron's interactions with other particles, such as other electrons or photons.
