OK, I understand that 'spin' is just an unfortunate name some someone gave to a particular quantum property and that particles do not actually spin. I also accept that I may never be able to understand what spin is without also understanding the mathematics involved. However, I am also told that 'spin' is an adequate analogy for the lay person because it gives rise to another quantised property of quantum objects called 'angular momentum'. This is what I would like to clear up or understand if possible. Is the 'angular momentum' of a particle also a metaphor for a particular mathematical property, or is a particle with angular momentum, able to exhibit a force that really is angular momentum. I have read thread no. 886279 which discussed the divorcing of angular momentum from spin, but I'm hoping to get a clearer picture.
